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

The lines y = 12x − 14 and y = -62 meet at x = -4. 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.
$12x - 14 = -62$
2
Add 14 to both sides:
$12x - 14 + 14 = -62 + 14 \ \Rightarrow\ 12x = -48$
3
Divide both sides by 12:
$\frac{12x}{12} = \frac{-48}{12} \ \Rightarrow\ x = -4$
4
Check: put x = -4 back into the equation.
$12\cdot(-4) - 14 = -48 - 14 = -62 \checkmark$
