Question

If 7(3x+9) and 21x + T are equivalent, what is the value of T?

Answer 1

`T=63`

Explanation:

Given:

`7(3x+9)` and
`21x+T` are equivalent.

Find value of T?

The
`7(3x+9) and 21x+T` are equivalent. therefore the equation is

`7(3x+9) = 21x+T`

`21x+63=21x+T`

`T = 21x+63-21x`

Here positive
`21x` and negative
`21x` is cancelled.

`T = 63`

So, the value of
`T=63`
