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

The lines y = 4x − 3 and y = -3 meet at x = 0. 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.
$4x - 3 = -3$
2
Add 3 to both sides:
$4x - 3 + 3 = -3 + 3 \ \Rightarrow\ 4x = 0$
3
Divide both sides by 4:
$\frac{4x}{4} = \frac{0}{4} \ \Rightarrow\ x = 0$
4
Check: put x = 0 back into the equation.
$4\cdot0 - 3 = 0 - 3 = -3 \checkmark$
