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

The lines y = 6x − 4 and y = 92 meet at x = 16. 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.
$6x - 4 = 92$
2
Add 4 to both sides:
$6x - 4 + 4 = 92 + 4 \ \Rightarrow\ 6x = 96$
3
Divide both sides by 6:
$\frac{6x}{6} = \frac{96}{6} \ \Rightarrow\ x = 16$
4
Check: put x = 16 back into the equation.
$6\cdot16 - 4 = 96 - 4 = 92 \checkmark$
