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

The lines y = 11x − 5 and y = 116 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 subtraction, then the multiplication.
$11x - 5 = 116$
2
Add 5 to both sides:
$11x - 5 + 5 = 116 + 5 \ \Rightarrow\ 11x = 121$
3
Divide both sides by 11:
$\frac{11x}{11} = \frac{121}{11} \ \Rightarrow\ x = 11$
4
Check: put x = 11 back into the equation.
$11\cdot11 - 5 = 121 - 5 = 116 \checkmark$
