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

The lines y = 6x − 8 and y = -62 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.
$6x - 8 = -62$
2
Add 8 to both sides:
$6x - 8 + 8 = -62 + 8 \ \Rightarrow\ 6x = -54$
3
Divide both sides by 6:
$\frac{6x}{6} = \frac{-54}{6} \ \Rightarrow\ x = -9$
4
Check: put x = -9 back into the equation.
$6\cdot(-9) - 8 = -54 - 8 = -62 \checkmark$
