The lines y = 6x + 5 and y = -37 meet at x = -7. 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.
$6x + 5 = -37$
2
Subtract 5 from both sides:
$6x + 5 - 5 = -37 - 5 \ \Rightarrow\ 6x = -42$
3
Divide both sides by 6:
$\frac{6x}{6} = \frac{-42}{6} \ \Rightarrow\ x = -7$
4
Check: put x = -7 back into the equation.
$6\cdot(-7) + 5 = -42 + 5 = -37 \checkmark$
