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

The lines y = 6x − 1 and y = -61 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.
$6x - 1 = -61$
2
Add 1 to both sides:
$6x - 1 + 1 = -61 + 1 \ \Rightarrow\ 6x = -60$
3
Divide both sides by 6:
$\frac{6x}{6} = \frac{-60}{6} \ \Rightarrow\ x = -10$
4
Check: put x = -10 back into the equation.
$6\cdot(-10) - 1 = -60 - 1 = -61 \checkmark$
