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

The lines y = 12x − 10 and y = 14 meet at x = 2. 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.
$12x - 10 = 14$
2
Add 10 to both sides:
$12x - 10 + 10 = 14 + 10 \ \Rightarrow\ 12x = 24$
3
Divide both sides by 12:
$\frac{12x}{12} = \frac{24}{12} \ \Rightarrow\ x = 2$
4
Check: put x = 2 back into the equation.
$12\cdot2 - 10 = 24 - 10 = 14 \checkmark$
