The lines y = 8x + 6 and y = 94 meet at x = 11. 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 addition, then the multiplication.
$8x + 6 = 94$
2
Subtract 6 from both sides:
$8x + 6 - 6 = 94 - 6 \ \Rightarrow\ 8x = 88$
3
Divide both sides by 8:
$\frac{8x}{8} = \frac{88}{8} \ \Rightarrow\ x = 11$
4
Check: put x = 11 back into the equation.
$8\cdot11 + 6 = 88 + 6 = 94 \checkmark$
