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]
