Question

if x=5/2,y=-3/4 then find (x+y)÷(x-y)​

Answer 1

Step-by-step explanation:

Because

=x:y=3:4

=(x/y)=(3/4).....(1)

∴ (7x+3y):(7x−3y)=(7x+3y)/(7x−3y)

=[7(x/y)+3]/[7(x/y)−3]....(on dividing numerator and denomenator by y)

=[7(3/4)+3]/[7(3/4)−3)]

=[(21/4)+3]:[(21/4)−3]....by using equation (1)

=(33/4)/(9/4)

=(33/4)×(4/9)

=(11/3)
