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

The lines y = 5x − 6 and y = 24 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 subtraction, then the multiplication.
$5x - 6 = 24$
2
Add 6 to both sides:
$5x - 6 + 6 = 24 + 6 \ \Rightarrow\ 5x = 30$
3
Divide both sides by 5:
$\frac{5x}{5} = \frac{30}{5} \ \Rightarrow\ x = 6$
4
Check: put x = 6 back into the equation.
$5\cdot6 - 6 = 30 - 6 = 24 \checkmark$
