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

The lines y = 6x − 6 and y = 60 meet at x = 11. 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.
$6x - 6 = 60$
2
Add 6 to both sides:
$6x - 6 + 6 = 60 + 6 \ \Rightarrow\ 6x = 66$
3
Divide both sides by 6:
$\frac{6x}{6} = \frac{66}{6} \ \Rightarrow\ x = 11$
4
Check: put x = 11 back into the equation.
$6\cdot11 - 6 = 66 - 6 = 60 \checkmark$
