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

The lines y = 11x − 2 and y = 141 meet at x = 13. 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.
$11x - 2 = 141$
2
Add 2 to both sides:
$11x - 2 + 2 = 141 + 2 \ \Rightarrow\ 11x = 143$
3
Divide both sides by 11:
$\frac{11x}{11} = \frac{143}{11} \ \Rightarrow\ x = 13$
4
Check: put x = 13 back into the equation.
$11\cdot13 - 2 = 143 - 2 = 141 \checkmark$
