The lines y = 5x + 6 and y = -14 meet at x = -4. 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.
$5x + 6 = -14$
2
Subtract 6 from both sides:
$5x + 6 - 6 = -14 - 6 \ \Rightarrow\ 5x = -20$
3
Divide both sides by 5:
$\frac{5x}{5} = \frac{-20}{5} \ \Rightarrow\ x = -4$
4
Check: put x = -4 back into the equation.
$5\cdot(-4) + 6 = -20 + 6 = -14 \checkmark$
