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

The lines y = 4x − 6 and y = -22 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.
$4x - 6 = -22$
2
Add 6 to both sides:
$4x - 6 + 6 = -22 + 6 \ \Rightarrow\ 4x = -16$
3
Divide both sides by 4:
$\frac{4x}{4} = \frac{-16}{4} \ \Rightarrow\ x = -4$
4
Check: put x = -4 back into the equation.
$4\cdot(-4) - 6 = -16 - 6 = -22 \checkmark$
