Question

a wire is 7x-3 metres long. a length 3x+4 metres is cut out of it for use. how muchwire is left​

Answer 1

Answer:

Total length of wire = 7x-3

Length of wire cut = 3x+4

Length of wire left = (7x-3) - (3x+4)

= (4x-7)m

Answer 2

Answer:

$\longrightarrow$ (4x - 7) m

Step-by-step explanation:

$\bigstar$ $\large\pmb{\mathfrak{To \ Find:-}}$

$\hookrightarrow$ Length of the wire left.

$\underline\mathcal{\red{Let's \ do \ it!!}}$

Total Length of the wire = (7x - 3) m

Length cut out = (3x + 4) m

$\therefore$ Length of the wire left = Original wire length - length of wire cut out.

$\implies$ (7x - 3) - (3x + 4) = Required length

$\implies$ Required Length = 7x - 3 - 3x - 4

$\implies$ Required Length = 7x - 3x - 3 - 4

$\implies$ Required Length = (4x - 7) m

Hence, the required Length that is the length of the wire left is (4x - 7) m.
