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

The lines y = 11x − 10 and y = 177 meet at x = 17. 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.
$11x - 10 = 177$
2
Add 10 to both sides:
$11x - 10 + 10 = 177 + 10 \ \Rightarrow\ 11x = 187$
3
Divide both sides by 11:
$\frac{11x}{11} = \frac{187}{11} \ \Rightarrow\ x = 17$
4
Check: put x = 17 back into the equation.
$11\cdot17 - 10 = 187 - 10 = 177 \checkmark$
