The lines y = 9x + 10 and y = -44 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.
$9x + 10 = -44$
2
Subtract 10 from both sides:
$9x + 10 - 10 = -44 - 10 \ \Rightarrow\ 9x = -54$
3
Divide both sides by 9:
$\frac{9x}{9} = \frac{-54}{9} \ \Rightarrow\ x = -6$
4
Check: put x = -6 back into the equation.
$9\cdot(-6) + 10 = -54 + 10 = -44 \checkmark$
