Question

if x/3 = 4/y = 12 then find the value of x+y and x-y.​

Answer 1

Answer:

84 and -12

Explanation:

x/3 = 4/y = 12

First lets solve x,

x/3 = 12

x = 12*3   (Transposition)

x = 36

Solve y,

4/y = 12

y = 12*4  (Transposition)

y = 48

Therefore,

x+y = 36+48 = 84

x-y = 36-48 = -12

Hope it helps!!!

Answer 2

Answer:

1/3 = y

36 = x

Explanation:

as, 36/3 = 12

and 4/12( simplified as 1/3) equals y
