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

The lines y = 9x − 6 and y = -96 meet at x = -10. 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.
$9x - 6 = -96$
2
Add 6 to both sides:
$9x - 6 + 6 = -96 + 6 \ \Rightarrow\ 9x = -90$
3
Divide both sides by 9:
$\frac{9x}{9} = \frac{-90}{9} \ \Rightarrow\ x = -10$
4
Check: put x = -10 back into the equation.
$9\cdot(-10) - 6 = -90 - 6 = -96 \checkmark$
