Question

-10\left(-\frac{1}{2}+\left(-\frac{7}{2}\right)+7y=25

Answer 1

`y=(47)/(14)`

Explanation:

Given

`-10\left(-(1)/(2)\right)+\left(-(7)/(2)\right)+7y=25`

Required

Solve for y

`-10\left(-(1)/(2)\right)+\left(-(7)/(2)\right)+7y=25`

Open brackets

`(10)/(2)-(7)/(2)+7y=25`

Collect Like Terms

`7y=25 -(10)/(2)+(7)/(2)`

Take L.C.M

`7y=(50-10+7)/(2)`

`7y=(47)/(2)`

Divide both sides by 7

`y=(47)/(2*7)`

`y=(47)/(14)`
