The lines y = 6x + 5 and y = -19 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.
$6x + 5 = -19$
2
Subtract 5 from both sides:
$6x + 5 - 5 = -19 - 5 \ \Rightarrow\ 6x = -24$
3
Divide both sides by 6:
$\frac{6x}{6} = \frac{-24}{6} \ \Rightarrow\ x = -4$
4
Check: put x = -4 back into the equation.
$6\cdot(-4) + 5 = -24 + 5 = -19 \checkmark$
