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

The lines y = 5x + 1 and y = -29 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.
$5x + 1 = -29$
2
Subtract 1 from both sides:
$5x + 1 - 1 = -29 - 1 \ \Rightarrow\ 5x = -30$
3
Divide both sides by 5:
$\frac{5x}{5} = \frac{-30}{5} \ \Rightarrow\ x = -6$
4
Check: put x = -6 back into the equation.
$5\cdot(-6) + 1 = -30 + 1 = -29 \checkmark$
