C. no solution
D. identity

Answer 1

Answer is "A".

My reasoning is, I did this in class.

Answer 2

A

Explanation:

Given

4 - t = 3(t - 1) - 5 ← distribute and simplify right side

4 - t = 3t - 3 - 5

4 - t = 3t - 8 ( subtract 4 from both sides )

- t = 3t - 12 ( subtract 3t from both sides )

- 4t = - 12 ( divide both sides by - 4 )

t = 3 → A
