Question

8-(3+b)=b-9 ion understand this​

Answer 1

b = 7

Explanation:

Given

8 - (3 + b) = b - 9 ← distribute parenthesis on the left by - 1

8 - 3 - b = b - 9, that is

5 - b = b - 9 ( subtract b from both sides )

5 - 2b = - 9 ( subtract 5 from both sides )

- 2b = - 14 ( divide both sides by - 2 )

b = 7
