The lines y = 6x + 11 and y = -37 meet at x = -8. 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.
$6x + 11 = -37$
2
Subtract 11 from both sides:
$6x + 11 - 11 = -37 - 11 \ \Rightarrow\ 6x = -48$
3
Divide both sides by 6:
$\frac{6x}{6} = \frac{-48}{6} \ \Rightarrow\ x = -8$
4
Check: put x = -8 back into the equation.
$6\cdot(-8) + 11 = -48 + 11 = -37 \checkmark$
