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

The lines y = 12x − 11 and y = -95 meet at x = -7. 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.
$12x - 11 = -95$
2
Add 11 to both sides:
$12x - 11 + 11 = -95 + 11 \ \Rightarrow\ 12x = -84$
3
Divide both sides by 12:
$\frac{12x}{12} = \frac{-84}{12} \ \Rightarrow\ x = -7$
4
Check: put x = -7 back into the equation.
$12\cdot(-7) - 11 = -84 - 11 = -95 \checkmark$
