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

The lines y = 4x + 6 and y = -14 meet at x = -5. 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.
$4x + 6 = -14$
2
Subtract 6 from both sides:
$4x + 6 - 6 = -14 - 6 \ \Rightarrow\ 4x = -20$
3
Divide both sides by 4:
$\frac{4x}{4} = \frac{-20}{4} \ \Rightarrow\ x = -5$
4
Check: put x = -5 back into the equation.
$4\cdot(-5) + 6 = -20 + 6 = -14 \checkmark$
