Question

4y/5b=L+s solve for B

Answer 1

`b = (4y)/(5l + 5s)`

Explanation:

`(4y)/(5b) = l + s`

multiplying through by the L.C.M. which is 5b

`(4y)/(5b) * 5b = (l + s) * 5b`

cancel out

4y =5bL+ 5bs

factorizing b out

4y=b ( 5L +5s ).

making be the subject by dividing through by ( 5L+ 5s )

`(4y)/(5l + 5s) = (b(5l + 5s))/(5l + 5s)`

`b = (4y)/(5l + 5s)`
