If 1/3t - 6 = 15 , what is the value of t ?

Question

Please explain how to solve this question.

Answer 1

Are we missing grouping parenthesis?

 

(1/3)t - 6 = 15

(1/3)t = 21

t = 21(3)

t = 63

 

1/(3t-6) = 15

1 = 15(3t-6)

1/15 = 3t - 6

3t = 1/15 + 6

t = (1/15 + 6)/3

t = 1/45 + 2 = 2 1/45

 

As written we have;

1/3t - 6 = 15

1/3t = 21

1 = 21(3t)

1/21 = 3t

t = (1/21)/3 = 1/63

 

You really MUST include the grouping parenthesis

in order to know what problem to solve.

Answer 2

t ≠ 0

1/3t - 6 = 15

1/3t = 21

3t/1 = 1/21

t = 1/63
