b+1.5(b+2)+15+2b-9=90

b + 1.5 (b + 2) + 15 + 2 b - 9 = 90

b = 18

Solution steps

b + 1.5 (b + 2) + 15 + 2 b - 9 = 90

Group like terms

b + 2 b + 1.5 (b + 2) + 15 - 9 = 90

to the right side

30 b + 15 (b + 2) - 90 = 750

Move

90

to the right side

30 b + 15 (b + 2) = 840

Expand

15 (b + 2) : 15 b + 30

30 b + 15 b + 30 = 840

Add similar elements:

30 b + 15 b = 45 b

45 b + 30 = 840

Move

30

to the right side

45 b = 810

Divide both sides by

45

b = 18
