The lines y = 2x − 14 and y = -24 meet at x = -5. 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.
$2x - 14 = -24$
2
Add 14 to both sides:
$2x - 14 + 14 = -24 + 14 \ \Rightarrow\ 2x = -10$
3
Divide both sides by 2:
$\frac{2x}{2} = \frac{-10}{2} \ \Rightarrow\ x = -5$
4
Check: put x = -5 back into the equation.
$2\cdot(-5) - 14 = -10 - 14 = -24 \checkmark$
