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

The lines y = 10x − 4 and y = 6 meet at x = 1. 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.
$10x - 4 = 6$
2
Add 4 to both sides:
$10x - 4 + 4 = 6 + 4 \ \Rightarrow\ 10x = 10$
3
Divide both sides by 10:
$\frac{10x}{10} = \frac{10}{10} \ \Rightarrow\ x = 1$
4
Check: put x = 1 back into the equation.
$10\cdot1 - 4 = 10 - 4 = 6 \checkmark$
