Question

How do you solve `\frac { 5} { 9} = \frac { 28} { b + 17}`?

Answer 1

What ever you do to one side of the equation, you must do to the other to keep them equal.

Explanation:

`9*[5/9]=[28/(b+17)]*9`

`(b+17) * [5]=[(28*(9))/(b+17)]*(b+17)`

`5(b+17)=28*(9)`

`[5b+85]-85=[252]-85`

`5b=167`

`b=167/5`
