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

The lines y = 5x − 10 and y = -60 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.
$5x - 10 = -60$
2
Add 10 to both sides:
$5x - 10 + 10 = -60 + 10 \ \Rightarrow\ 5x = -50$
3
Divide both sides by 5:
$\frac{5x}{5} = \frac{-50}{5} \ \Rightarrow\ x = -10$
4
Check: put x = -10 back into the equation.
$5\cdot(-10) - 10 = -50 - 10 = -60 \checkmark$
