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

The lines y = 4x + 14 and y = -10 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.
$4x + 14 = -10$
2
Subtract 14 from both sides:
$4x + 14 - 14 = -10 - 14 \ \Rightarrow\ 4x = -24$
3
Divide both sides by 4:
$\frac{4x}{4} = \frac{-24}{4} \ \Rightarrow\ x = -6$
4
Check: put x = -6 back into the equation.
$4\cdot(-6) + 14 = -24 + 14 = -10 \checkmark$
