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

The lines y = 10x − 6 and y = -106 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.
$10x - 6 = -106$
2
Add 6 to both sides:
$10x - 6 + 6 = -106 + 6 \ \Rightarrow\ 10x = -100$
3
Divide both sides by 10:
$\frac{10x}{10} = \frac{-100}{10} \ \Rightarrow\ x = -10$
4
Check: put x = -10 back into the equation.
$10\cdot(-10) - 6 = -100 - 6 = -106 \checkmark$
