Answer 1

Answer:

$b) \: \: \frac{2b}{3} - 5 = 3 \\ \frac{2b}{3} - \frac{15}{3} = 3 \\ \frac{2b - 15}{3} = 3 \\ 2b - 13 = 3 \times 3 \\ 2b = 9 + 13 \\ 2b = 22 \\ b = \frac{22}{2} \\ b = 11 \\ \\ c) \: 4 + 3(t + 2) = 16 \\ 4 + 3t + 6 = 16 \\ 3t + 10 = 16 \\ 3t = 6 \\ t = \frac{6}{3} \\ t = 2$

Hope it helps you

Answer 2

Answer:

b) 2b/3 - 5 = 3

2b/3 = 3 + 5

2b/3 = 8

2b = 8 × 3

2b = 24

b = 24/2

b = 12

c) 4 + 3( t + 2) = 16

4 + 3t + 6 = 16

3t + 10 = 26

3t = 16 - 10

3t = 6

t = 6/3

t = 2
