Explain it step by step in chat Make a short video of it

The lines y = 2x − 14 and y = 24 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 subtraction, then the multiplication.
$2x - 14 = 24$
2
Add 14 to both sides:
$2x - 14 + 14 = 24 + 14 \ \Rightarrow\ 2x = 38$
3
Divide both sides by 2:
$\frac{2x}{2} = \frac{38}{2} \ \Rightarrow\ x = 19$
4
Check: put x = 19 back into the equation.
$2\cdot19 - 14 = 38 - 14 = 24 \checkmark$
