Question

find (x+y)÷(x-y) if x=5/2,y=-3/4​

Answer 1

Step-by-step explanation:

we have to find first X + Y X + Y = 5/2 + (- 3/4)

=5/2-3/4 Rightarrow10-3/4 Rightarrow7/4

Now we find X - Y

X-Y=5/2-(-3/4) Rightarrow5/2+

3/4 Rightarrow10+3/4 Rightarrow13/4

Now X +Y/X-Y=(7/4)/(13/4) Rightarrow7/13

Answer 2

Answer:

If

(x+2,4)=(5,2x+y)

Then

x+2=5

→x=3…(1)

4=2x+y

→4=2×3+y..( from1)

→-2=y

→y= -2
