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

The lines y = 5x − 14 and y = 1 meet at x = 3. 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.
$5x - 14 = 1$
2
Add 14 to both sides:
$5x - 14 + 14 = 1 + 14 \ \Rightarrow\ 5x = 15$
3
Divide both sides by 5:
$\frac{5x}{5} = \frac{15}{5} \ \Rightarrow\ x = 3$
4
Check: put x = 3 back into the equation.
$5\cdot3 - 14 = 15 - 14 = 1 \checkmark$
