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

The lines y = 11x − 8 and y = 201 meet at x = 19. 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.
$11x - 8 = 201$
2
Add 8 to both sides:
$11x - 8 + 8 = 201 + 8 \ \Rightarrow\ 11x = 209$
3
Divide both sides by 11:
$\frac{11x}{11} = \frac{209}{11} \ \Rightarrow\ x = 19$
4
Check: put x = 19 back into the equation.
$11\cdot19 - 8 = 209 - 8 = 201 \checkmark$
