The lines y = 6x + 2 and y = -34 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.
$6x + 2 = -34$
2
Subtract 2 from both sides:
$6x + 2 - 2 = -34 - 2 \ \Rightarrow\ 6x = -36$
3
Divide both sides by 6:
$\frac{6x}{6} = \frac{-36}{6} \ \Rightarrow\ x = -6$
4
Check: put x = -6 back into the equation.
$6\cdot(-6) + 2 = -36 + 2 = -34 \checkmark$
