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

The lines y = 6x + 1 and y = -5 meet at x = -1. 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 addition, then the multiplication.
$6x + 1 = -5$
2
Subtract 1 from both sides:
$6x + 1 - 1 = -5 - 1 \ \Rightarrow\ 6x = -6$
3
Divide both sides by 6:
$\frac{6x}{6} = \frac{-6}{6} \ \Rightarrow\ x = -1$
4
Check: put x = -1 back into the equation.
$6\cdot(-1) + 1 = -6 + 1 = -5 \checkmark$
