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

The lines y = 6x − 13 and y = 59 meet at x = 12. 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.
$6x - 13 = 59$
2
Add 13 to both sides:
$6x - 13 + 13 = 59 + 13 \ \Rightarrow\ 6x = 72$
3
Divide both sides by 6:
$\frac{6x}{6} = \frac{72}{6} \ \Rightarrow\ x = 12$
4
Check: put x = 12 back into the equation.
$6\cdot12 - 13 = 72 - 13 = 59 \checkmark$
