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

The lines y = 4x + 10 and y = -6 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 addition, then the multiplication.
$4x + 10 = -6$
2
Subtract 10 from both sides:
$4x + 10 - 10 = -6 - 10 \ \Rightarrow\ 4x = -16$
3
Divide both sides by 4:
$\frac{4x}{4} = \frac{-16}{4} \ \Rightarrow\ x = -4$
4
Check: put x = -4 back into the equation.
$4\cdot(-4) + 10 = -16 + 10 = -6 \checkmark$
