Answer:

We need to solve each equation:

1. 2x - 5 = x

2x - x = 5

x = 5 ✅

2. -3b + 1 = 3b -5

5 + 1 = 3b + 3b

6 = 6b

b = 1 ✅

3. (1/2)t + 7 = (3/2)t - 4

t + 14 = 3t - 8

2t = 22

t = 11 ✅

4. -2.3 + 1.2x = 5.9 - 2.9x

2.9x + 1.2x = 5.9 + 2.3

4.1x = 8.2

x = 2 ✅

5. -7y -21 = -3y - 21

-21 + 21 = -3y + 7y

0 = 4y

y = 0 ✅
