The lines y = 11x − 6 and y = 93 meet at x = 9. 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.
$11x - 6 = 93$
2
Add 6 to both sides:
$11x - 6 + 6 = 93 + 6 \ \Rightarrow\ 11x = 99$
3
Divide both sides by 11:
$\frac{11x}{11} = \frac{99}{11} \ \Rightarrow\ x = 9$
4
Check: put x = 9 back into the equation.
$11\cdot9 - 6 = 99 - 6 = 93 \checkmark$
