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

The lines y = 11x − 3 and y = 19 meet at x = 2. 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.
$11x - 3 = 19$
2
Add 3 to both sides:
$11x - 3 + 3 = 19 + 3 \ \Rightarrow\ 11x = 22$
3
Divide both sides by 11:
$\frac{11x}{11} = \frac{22}{11} \ \Rightarrow\ x = 2$
4
Check: put x = 2 back into the equation.
$11\cdot2 - 3 = 22 - 3 = 19 \checkmark$
