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

The lines y = 4x − 3 and y = 41 meet at x = 11. 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.
$4x - 3 = 41$
2
Add 3 to both sides:
$4x - 3 + 3 = 41 + 3 \ \Rightarrow\ 4x = 44$
3
Divide both sides by 4:
$\frac{4x}{4} = \frac{44}{4} \ \Rightarrow\ x = 11$
4
Check: put x = 11 back into the equation.
$4\cdot11 - 3 = 44 - 3 = 41 \checkmark$
