1. Solve: - 3x + 1 = 7

2. 5x - 23 = 72

3. - 34 = b/2 - 23

4. (1/3) y - 7 = 3

5. - 2t - 13 = - 3

1. - 2 = x

2. 19 = x

3. - 22 = b

4. 30 = y

5. - 5 = t

Step-by-step explanation:

1. - 3x = 6 [-1 to the right side of the equivalence symbol]

2. 5x = 95 [23 to the right side of the equivalence symbol]

3. ᵇ/₂ = - 11 [23 to the left side of the equivalence symbol]

4. ⅓y = 10 [7 to the right side of the equivalence symbol]

5. - 2t = 10 [13 to the right side of the equivalence symbol]
