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

The lines y = 11x + 15 and y = -95 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 addition, then the multiplication.
$11x + 15 = -95$
2
Subtract 15 from both sides:
$11x + 15 - 15 = -95 - 15 \ \Rightarrow\ 11x = -110$
3
Divide both sides by 11:
$\frac{11x}{11} = \frac{-110}{11} \ \Rightarrow\ x = -10$
4
Check: put x = -10 back into the equation.
$11\cdot(-10) + 15 = -110 + 15 = -95 \checkmark$
