Question

a linear equation in one variable is 3t+5=9t -7​

Answer 1

Answer:

ANSWER = 2

Step-by-step explanation:

3t+5=9t-7

-(transposing)

- 5+7=9t-3t

- 12 = 6t

- t   = 12/6 = 2 .

Answer 2

Answer:

27t² + 24t + 35 or 6,18

Step-by-step explanation:

9t ( 3t + 5 ) - 7 ( 3t + 5 )

= 27t² + 45t - 21t + 35

= 27t² + 24t + 35

or

3t + 5 = 9t - 7​

= 7 + 5 = 9t - 3t

= 12 = 6t

= t = 12/6

= t = 2

* 3t = 3 × 2 = 6

 9t = 9 × 2 = 18
