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

The lines y = 11x − 4 and y = -48 meet at x = -4. 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.
$11x - 4 = -48$
2
Add 4 to both sides:
$11x - 4 + 4 = -48 + 4 \ \Rightarrow\ 11x = -44$
3
Divide both sides by 11:
$\frac{11x}{11} = \frac{-44}{11} \ \Rightarrow\ x = -4$
4
Check: put x = -4 back into the equation.
$11\cdot(-4) - 4 = -44 - 4 = -48 \checkmark$
