The lines y = 11x + 3 and y = -41 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.
$11x + 3 = -41$
2
Subtract 3 from both sides:
$11x + 3 - 3 = -41 - 3 \ \Rightarrow\ 11x = -44$
3
Divide both sides by 11:
$\frac{11x}{11} = \frac{-44}{11} \ \Rightarrow\ x = -4$
4
Check: put x = -4 back into the equation.
$11\cdot(-4) + 3 = -44 + 3 = -41 \checkmark$
