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

The lines y = 10x − 14 and y = -34 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.
$10x - 14 = -34$
2
Add 14 to both sides:
$10x - 14 + 14 = -34 + 14 \ \Rightarrow\ 10x = -20$
3
Divide both sides by 10:
$\frac{10x}{10} = \frac{-20}{10} \ \Rightarrow\ x = -2$
4
Check: put x = -2 back into the equation.
$10\cdot(-2) - 14 = -20 - 14 = -34 \checkmark$
