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

The lines y = 4x − 14 and y = -26 meet at x = -3. 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.
$4x - 14 = -26$
2
Add 14 to both sides:
$4x - 14 + 14 = -26 + 14 \ \Rightarrow\ 4x = -12$
3
Divide both sides by 4:
$\frac{4x}{4} = \frac{-12}{4} \ \Rightarrow\ x = -3$
4
Check: put x = -3 back into the equation.
$4\cdot(-3) - 14 = -12 - 14 = -26 \checkmark$
