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

The lines y = 11x − 14 and y = -25 meet at x = -1. 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.
$11x - 14 = -25$
2
Add 14 to both sides:
$11x - 14 + 14 = -25 + 14 \ \Rightarrow\ 11x = -11$
3
Divide both sides by 11:
$\frac{11x}{11} = \frac{-11}{11} \ \Rightarrow\ x = -1$
4
Check: put x = -1 back into the equation.
$11\cdot(-1) - 14 = -11 - 14 = -25 \checkmark$
