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

The lines y = 6x − 1 and y = 29 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.
$6x - 1 = 29$
2
Add 1 to both sides:
$6x - 1 + 1 = 29 + 1 \ \Rightarrow\ 6x = 30$
3
Divide both sides by 6:
$\frac{6x}{6} = \frac{30}{6} \ \Rightarrow\ x = 5$
4
Check: put x = 5 back into the equation.
$6\cdot5 - 1 = 30 - 1 = 29 \checkmark$
