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

The lines y = 11x − 15 and y = 95 meet at x = 10. 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.
$11x - 15 = 95$
2
Add 15 to both sides:
$11x - 15 + 15 = 95 + 15 \ \Rightarrow\ 11x = 110$
3
Divide both sides by 11:
$\frac{11x}{11} = \frac{110}{11} \ \Rightarrow\ x = 10$
4
Check: put x = 10 back into the equation.
$11\cdot10 - 15 = 110 - 15 = 95 \checkmark$
