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

The lines y = 6x − 2 and y = 58 meet at x = 10. 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.
$6x - 2 = 58$
2
Add 2 to both sides:
$6x - 2 + 2 = 58 + 2 \ \Rightarrow\ 6x = 60$
3
Divide both sides by 6:
$\frac{6x}{6} = \frac{60}{6} \ \Rightarrow\ x = 10$
4
Check: put x = 10 back into the equation.
$6\cdot10 - 2 = 60 - 2 = 58 \checkmark$
