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

The lines y = 11x − 3 and y = 195 meet at x = 18. 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.
$11x - 3 = 195$
2
Add 3 to both sides:
$11x - 3 + 3 = 195 + 3 \ \Rightarrow\ 11x = 198$
3
Divide both sides by 11:
$\frac{11x}{11} = \frac{198}{11} \ \Rightarrow\ x = 18$
4
Check: put x = 18 back into the equation.
$11\cdot18 - 3 = 198 - 3 = 195 \checkmark$
