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

The lines y = 11x − 6 and y = 214 meet at x = 20. 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.
$11x - 6 = 214$
2
Add 6 to both sides:
$11x - 6 + 6 = 214 + 6 \ \Rightarrow\ 11x = 220$
3
Divide both sides by 11:
$\frac{11x}{11} = \frac{220}{11} \ \Rightarrow\ x = 20$
4
Check: put x = 20 back into the equation.
$11\cdot20 - 6 = 220 - 6 = 214 \checkmark$
