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

The lines y = 10x − 2 and y = -62 meet at x = -6. 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.
$10x - 2 = -62$
2
Add 2 to both sides:
$10x - 2 + 2 = -62 + 2 \ \Rightarrow\ 10x = -60$
3
Divide both sides by 10:
$\frac{10x}{10} = \frac{-60}{10} \ \Rightarrow\ x = -6$
4
Check: put x = -6 back into the equation.
$10\cdot(-6) - 2 = -60 - 2 = -62 \checkmark$
