Question

Rearrange they following formula to make x the subject. Give your answer in its simplest form. 2(x- y)=7y-3

Answer 1

x =
`(9y-3)/(2)`

Explanation:

2(x - y) = 7y - 3 ← distribute parenthesis on left side by 2

2x - 2y = 7y - 3 ( add 2y to both sides )

2x - 2y + 2y = 7y + 2y - 3 ( simplify )

2x = 9y - 3 ( isolate x by dividing both sides by 2 )

`(2)/(2)` x =
`(9y-3)/(2)` , that is

x =
`(9y-3)/(2)`
