Treat the problem as a set of linear equations,
4x + 2 = 0
3x - 7 = 0
Because both equations equal 0, you can simplify it to
4x + 2 = 3x - 7.
Let's walk through this step by step.
The goal is to find the value of x, or isolate x on one side.
Let's start by moving non-x values.
4x + 2 = 3x - 7
Add 7 on both sides
4x + 9 = 3x
Now, we should combine the x terms on one side.
4x + 9 = 3x
Subtract 4x from both sides
9 = -x
Then, we can multiply both sides by -1 to isolate x.
-x = 9
x = -9
