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

The lines y = 6x − 8 and y = 94 meet at x = 17. 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.
$6x - 8 = 94$
2
Add 8 to both sides:
$6x - 8 + 8 = 94 + 8 \ \Rightarrow\ 6x = 102$
3
Divide both sides by 6:
$\frac{6x}{6} = \frac{102}{6} \ \Rightarrow\ x = 17$
4
Check: put x = 17 back into the equation.
$6\cdot17 - 8 = 102 - 8 = 94 \checkmark$
