The lines y = 11x − 7 and y = 59 meet at x = 6. 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.
$11x - 7 = 59$
2
Add 7 to both sides:
$11x - 7 + 7 = 59 + 7 \ \Rightarrow\ 11x = 66$
3
Divide both sides by 11:
$\frac{11x}{11} = \frac{66}{11} \ \Rightarrow\ x = 6$
4
Check: put x = 6 back into the equation.
$11\cdot6 - 7 = 66 - 7 = 59 \checkmark$
