Answer 1

Required Answer:

Given pair of expression :

`\longrightarrow \sf {(4x -7) \: and \: (7-4x) }`

Solution :

Firstly put the sign of addition (+) at the place of and.

`\longrightarrow \sf {(4x -7) + (7-4x) }`

Now, remove the brackets.

`\longrightarrow \sf {4x -7 + 7-4x }`

Group like terms. Here, 4x and -4x ; -7 and +7 are like terms.

`\longrightarrow \sf {\cancel{4x -4x} \cancel{ -7 + 7}}`

`\implies \sf \red {0 }`

So, the answer is 0.
