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

The lines y = 4x − 3 and y = -35 meet at x = -8. 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.
$4x - 3 = -35$
2
Add 3 to both sides:
$4x - 3 + 3 = -35 + 3 \ \Rightarrow\ 4x = -32$
3
Divide both sides by 4:
$\frac{4x}{4} = \frac{-32}{4} \ \Rightarrow\ x = -8$
4
Check: put x = -8 back into the equation.
$4\cdot(-8) - 3 = -32 - 3 = -35 \checkmark$
