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

The lines y = 12x − 1 and y = 59 meet at x = 5. 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.
$12x - 1 = 59$
2
Add 1 to both sides:
$12x - 1 + 1 = 59 + 1 \ \Rightarrow\ 12x = 60$
3
Divide both sides by 12:
$\frac{12x}{12} = \frac{60}{12} \ \Rightarrow\ x = 5$
4
Check: put x = 5 back into the equation.
$12\cdot5 - 1 = 60 - 1 = 59 \checkmark$
