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

The lines y = 6x − 4 and y = -34 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 subtraction, then the multiplication.
$6x - 4 = -34$
2
Add 4 to both sides:
$6x - 4 + 4 = -34 + 4 \ \Rightarrow\ 6x = -30$
3
Divide both sides by 6:
$\frac{6x}{6} = \frac{-30}{6} \ \Rightarrow\ x = -5$
4
Check: put x = -5 back into the equation.
$6\cdot(-5) - 4 = -30 - 4 = -34 \checkmark$
