Required Answer:
Given pair of expression :
[tex] \longrightarrow \sf {(4x -7) \: and \: (7-4x) } [/tex]
Solution :
Firstly put the sign of addition (+) at the place of and.
[tex] \longrightarrow \sf {(4x -7) + (7-4x) } [/tex]
Now, remove the brackets.
[tex] \longrightarrow \sf {4x -7 + 7-4x } [/tex]
Group like terms. Here, 4x and -4x ; -7 and +7 are like terms.
[tex] \longrightarrow \sf {\cancel{4x -4x} \cancel{ -7 + 7}} [/tex]
[tex] \implies \sf \red {0 } [/tex]
So, the answer is 0.
