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

The lines y = 7x − 5 and y = 44 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 subtraction, then the multiplication.
$7x - 5 = 44$
2
Add 5 to both sides:
$7x - 5 + 5 = 44 + 5 \ \Rightarrow\ 7x = 49$
3
Divide both sides by 7:
$\frac{7x}{7} = \frac{49}{7} \ \Rightarrow\ x = 7$
4
Check: put x = 7 back into the equation.
$7\cdot7 - 5 = 49 - 5 = 44 \checkmark$
