Answer:
The amount of wire left is 4x + 1
Step-by-step explanation:
Initially, the wire is (7x – 3) meters long.
A length of (3x – 4) meters is cut.
How much wire is left?
Initial amount subtracted by the amount that is cut. So
(7x – 3) – (3x – 4) = 7x – 3 – 3x + 4
We combine the like terms
7x – 3x – 3 + 4 = 4x + 1
The amount of wire left is 4x + 1
