Answer:

[tex]T=63[/tex]

Step-by-step explanation:

Given:

[tex]7(3x+9)[/tex]  and [tex]21x+T[/tex] are equivalent.

Find value of T?

The [tex]7(3x+9) and 21x+T[/tex] are equivalent. therefore the equation is

[tex]7(3x+9) = 21x+T[/tex]

[tex]21x+63=21x+T[/tex]

[tex]T = 21x+63-21x[/tex]

Here positive [tex]21x[/tex] and negative [tex]21x[/tex] is cancelled.

[tex]T = 63[/tex]

So, the value of [tex]T=63[/tex]
