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
