Question

Solve for y using Proportion.

y/p-q = y/p+q



A.) 0


B.) y/q


C.) 1/2q

Answer 1

The answer would be A) 0

Explanation:

In order to find this, cross multiply to solve.

y/p-q = y/p+q

y(p + q) = y(p - q)

yp + yq = yp - yq -----> Subtract yp from both sides

yq = -yq -----> Add yq to both sides

2yq = 0 ------> divide by 2q

y = 0

Answer 2

The correct answer is option A.

Explanation:

`(y)/(p-q)=(y)/(p+q)`

Solving by proportions :

`a:b:: c:d`

`ad=bc`

So,

`y* (p+q)=y* (p-q)`

`p+q=p-q`

`p-p=-q-q`

`0=-2q`

q = 0

Hence, the correct answer is option A.
