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

The lines y = 11x − 13 and y = 174 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.
$11x - 13 = 174$
2
Add 13 to both sides:
$11x - 13 + 13 = 174 + 13 \ \Rightarrow\ 11x = 187$
3
Divide both sides by 11:
$\frac{11x}{11} = \frac{187}{11} \ \Rightarrow\ x = 17$
4
Check: put x = 17 back into the equation.
$11\cdot17 - 13 = 187 - 13 = 174 \checkmark$
