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

The lines y = 3x − 11 and y = -41 meet at x = -10. 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.
$3x - 11 = -41$
2
Add 11 to both sides:
$3x - 11 + 11 = -41 + 11 \ \Rightarrow\ 3x = -30$
3
Divide both sides by 3:
$\frac{3x}{3} = \frac{-30}{3} \ \Rightarrow\ x = -10$
4
Check: put x = -10 back into the equation.
$3\cdot(-10) - 11 = -30 - 11 = -41 \checkmark$
