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

The lines y = 6x + 4 and y = -32 meet at x = -6. 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.
$6x + 4 = -32$
2
Subtract 4 from both sides:
$6x + 4 - 4 = -32 - 4 \ \Rightarrow\ 6x = -36$
3
Divide both sides by 6:
$\frac{6x}{6} = \frac{-36}{6} \ \Rightarrow\ x = -6$
4
Check: put x = -6 back into the equation.
$6\cdot(-6) + 4 = -36 + 4 = -32 \checkmark$
