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

The lines y = 4x − 6 and y = 10 meet at x = 4. 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.
$4x - 6 = 10$
2
Add 6 to both sides:
$4x - 6 + 6 = 10 + 6 \ \Rightarrow\ 4x = 16$
3
Divide both sides by 4:
$\frac{4x}{4} = \frac{16}{4} \ \Rightarrow\ x = 4$
4
Check: put x = 4 back into the equation.
$4\cdot4 - 6 = 16 - 6 = 10 \checkmark$
