Answer:

b = [tex]\frac{7}{5}[/tex] = 1.4

Step-by-step explanation:

[tex]\frac{2b - 3 }{5}[/tex] = [tex]\frac{b - 2}{15}[/tex]

15(2b - 3) = 5(b - 2)

30b - 45 = 5b - 10

25b = 35

5b = 7

b = [tex]\frac{7}{5}[/tex] = 1.4

Check the answer:

[tex]\frac{2(1.4)-3}{5}[/tex] = [tex]\frac{1.4-2}{15}[/tex]

- [tex]\frac{0.2}{5}[/tex] = - [tex]\frac{0.6}{15}[/tex]

- 0.04 = - 0.04
