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

The lines y = 9x − 5 and y = -41 meet at x = -4. 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.
$9x - 5 = -41$
2
Add 5 to both sides:
$9x - 5 + 5 = -41 + 5 \ \Rightarrow\ 9x = -36$
3
Divide both sides by 9:
$\frac{9x}{9} = \frac{-36}{9} \ \Rightarrow\ x = -4$
4
Check: put x = -4 back into the equation.
$9\cdot(-4) - 5 = -36 - 5 = -41 \checkmark$
