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

The lines y = 11x − 1 and y = 32 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.
$11x - 1 = 32$
2
Add 1 to both sides:
$11x - 1 + 1 = 32 + 1 \ \Rightarrow\ 11x = 33$
3
Divide both sides by 11:
$\frac{11x}{11} = \frac{33}{11} \ \Rightarrow\ x = 3$
4
Check: put x = 3 back into the equation.
$11\cdot3 - 1 = 33 - 1 = 32 \checkmark$
