Question

A wire is (7x – 3) metres long. A length of (3x – 4) metres is cut for use.

How much wire is left?​

Answer 1

Step-by-step explanation:

(7x-3)-(3x-4)

7x-3-3x+4

7x-3x-3+4

4x+1

Answer 2

$7x - 3 + 3x + 4 \\ = 7x + 3x - 3 + 4 \\ = 10x + 1 \\ x = \frac{10}{1 } \\ x = 10$

$hence \: 10 \: m \: wire \: is \:left$
