We’re just going to solve for the absolute value of x plus 7.

Worked example: absolute value equation with two solutions (video) | Khan Academy

So you could almost treat this expression– the absolute value of x plus 7, you can just treat it as a variable, and then once you solve for that, it becomes a simpler absolute value problem. If these two things are equal and we are being told that they are, then if you add something on this side, the only way that the equality will hold is if you still do it on the left-hand side. So how can we reason through this?

Solve absolute value equations.

Quadratic functions and inequalities. Algebra 2 Quadratic functions and inequalities Overview How to graph quadratic functions How to solve quadratic equations The Quadratic formula Standard deviation and normal distribution.

How to solve system of linear equations. Let’s try to solve for not x first. Video transcript We’re asked to solve for x. This Algebra 2 math course is divided into 13 chapters and each chapter is divided into several lessons.

Algebra 2 How to graph functions and linear equations Overview Functions and linear equations Graph functions and relations Graph inequalities. We’re just subtracting 7 from both sides. Now the key here– at a,gebra it looks kind of daunting. So let’s try to do that. So our left-hand side, if I have 8 of something– and in this case the something is absolute values of x plus 7’s– but if I have 8 of something and I add 6 of that same something, I now have 14 of that something.

Intro to absolute value equations and graphs. Answerd mathematics and probability. And then we’re left with 6 minus 4, which is just 2. Algebra 2 Polynomial functions Overview Basic knowledge of polynomial functions Remainder and factor theorems Roots and zeros Descartes’ rule of sign Composition of functions. Under each lesson you will find theory, examples and video lessons. So that’s one possibility for x.

And just think about that for a second.

And I want to get all of these constant terms on to the anseers side. Search Pre-Algebra All courses. So that’s going to be equal to 2.

So now let’s just solve for x. And so what does this get us? Easiest way is to subtract 4 right over there, but if we do it on the left-hand side, we have to do it on the right-hand side as well.

Let me just rewrite this equation so that the absolute algebrx really pop out. So I want to get rid of this positive 4. Algebra 2 is the third math course in high school and will guide you through among other things linear equations, inequalities, graphs, matrices, polynomials and radical expressions, quadratic equations, functions, exponential and logarithmic expressions, sequences and series, probability and trigonometry.

Easiest way to get rid of it is to add 6 times the absolute value of x plus 7 to the right-hand side. So just as promised, we’ve now answerd for the absolute value of x plus 7, but we really need to solve for x.

But the way to think abswers this is if you could solve for the absolute value expression, you could then– it then turns into a much simpler problem, then you can take it from there. How to graph functions and linear equations. So this is 8 times the absolute value of x plus 7 plus in that same color– is equal to negative 6 times the absolute value of x plus 7 plus 6. It’s this complex equation.

So let’s do that, so plus 6 times the absolute value of x plus 7. The negative 6 and the 6 x plus 7’s cancel out, or absolute values of x plus 7’s cancel out, and that was intentional. Polynomials and radical expressions.

Now just as promised, we want to solve for the absolute value of x plus 7, so let’s divide both sides by 14 to anewers rid of that coefficient there, or that factor, or whatever you want to call it, the thing that’s multiplying the absolute value of x plus 7.
