    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
