The lines y = 2x + 6 and y = 44 meet at x = 19. 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.
$2x + 6 = 44$
2
Subtract 6 from both sides:
$2x + 6 - 6 = 44 - 6 \ \Rightarrow\ 2x = 38$
3
Divide both sides by 2:
$\frac{2x}{2} = \frac{38}{2} \ \Rightarrow\ x = 19$
4
Check: put x = 19 back into the equation.
$2\cdot19 + 6 = 38 + 6 = 44 \checkmark$
