The lines y = 11x + 2 and y = -64 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 addition, then the multiplication.
$11x + 2 = -64$
2
Subtract 2 from both sides:
$11x + 2 - 2 = -64 - 2 \ \Rightarrow\ 11x = -66$
3
Divide both sides by 11:
$\frac{11x}{11} = \frac{-66}{11} \ \Rightarrow\ x = -6$
4
Check: put x = -6 back into the equation.
$11\cdot(-6) + 2 = -66 + 2 = -64 \checkmark$
