Explain it step by step in chat Make a short video of it

The lines y = 2x − 14 and y = -32 meet at x = -9. The solution of the equation is the x-coordinate of the point where the two sides are equal.

How to work it out

1
The goal is to get x alone. Undo the operations in the opposite order: first the subtraction, then the multiplication.
$2x - 14 = -32$
2
Add 14 to both sides:
$2x - 14 + 14 = -32 + 14 \ \Rightarrow\ 2x = -18$
3
Divide both sides by 2:
$\frac{2x}{2} = \frac{-18}{2} \ \Rightarrow\ x = -9$
4
Check: put x = -9 back into the equation.
$2\cdot(-9) - 14 = -18 - 14 = -32 \checkmark$
