Question

1/2b-7=5.5 slove for b

Answer 1

B=25

Explanation1

​1/2b−7=5.5

Add 7 to both sides.

1/2b=5.5+7

​ b=5.5+7

Add 5.5 and 7 to get 12.5.

1/2 b=12.5

Multiply both sides by 2, the reciprocal of 1/2.

b=12.5×2

Multiply 12.5 and 2 to get 25.

b=25

Answer 2

b = 25

Explanation:

Given

`(1)/(2)` b - 7 = 5.5 ( multiply through by 2 to clear the fraction )

b - 14 = 11 ( add 14 to both sides )

b = 25
