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

The lines y = 5x + 1 and y = -34 meet at x = -7. 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.
$5x + 1 = -34$
2
Subtract 1 from both sides:
$5x + 1 - 1 = -34 - 1 \ \Rightarrow\ 5x = -35$
3
Divide both sides by 5:
$\frac{5x}{5} = \frac{-35}{5} \ \Rightarrow\ x = -7$
4
Check: put x = -7 back into the equation.
$5\cdot(-7) + 1 = -35 + 1 = -34 \checkmark$
