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

The lines y = 6x − 10 and y = 38 meet at x = 8. 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.
$6x - 10 = 38$
2
Add 10 to both sides:
$6x - 10 + 10 = 38 + 10 \ \Rightarrow\ 6x = 48$
3
Divide both sides by 6:
$\frac{6x}{6} = \frac{48}{6} \ \Rightarrow\ x = 8$
4
Check: put x = 8 back into the equation.
$6\cdot8 - 10 = 48 - 10 = 38 \checkmark$
