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

The lines y = 8x − 2 and y = 110 meet at x = 14. 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.
$8x - 2 = 110$
2
Add 2 to both sides:
$8x - 2 + 2 = 110 + 2 \ \Rightarrow\ 8x = 112$
3
Divide both sides by 8:
$\frac{8x}{8} = \frac{112}{8} \ \Rightarrow\ x = 14$
4
Check: put x = 14 back into the equation.
$8\cdot14 - 2 = 112 - 2 = 110 \checkmark$
