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

The lines y = 5x − 3 and y = 62 meet at x = 13. 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.
$5x - 3 = 62$
2
Add 3 to both sides:
$5x - 3 + 3 = 62 + 3 \ \Rightarrow\ 5x = 65$
3
Divide both sides by 5:
$\frac{5x}{5} = \frac{65}{5} \ \Rightarrow\ x = 13$
4
Check: put x = 13 back into the equation.
$5\cdot13 - 3 = 65 - 3 = 62 \checkmark$
