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

The lines y = 11x − 10 and y = -98 meet at x = -8. 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.
$11x - 10 = -98$
2
Add 10 to both sides:
$11x - 10 + 10 = -98 + 10 \ \Rightarrow\ 11x = -88$
3
Divide both sides by 11:
$\frac{11x}{11} = \frac{-88}{11} \ \Rightarrow\ x = -8$
4
Check: put x = -8 back into the equation.
$11\cdot(-8) - 10 = -88 - 10 = -98 \checkmark$
