Question

find(x+y) :-(x+y)if x=. -6/5 Y=8/9​

Answer 1

Answer:

Given x: y = 3: 5 We can write above equation as x/y = 3/5 5x = 3y x = 3y/5 By substituting the value of x in given equation 3x + 4y: 8x + 5y we get, 3x + 4y: 8x + 5y = 3 (3y/5) + 4y: 8 (3y/5) + 5y = (9y + 20y)/5: (24y + 25y)/5 = 29y/5: 49y/5 = 29y: 49y = 29: 49Read more on Sarthaks.com - https://www.sarthaks.com/684735/if-x-y-3-5-find-the-ratio-3x-4y-8x-5y

Answer 2

Answer:

(x+y) = -14/45

Explanation:

(x+y) = ?

x = -6/5

y = 8/9

So, (x+y) = [-6/5] + [8/9]

= [-54/45] + [40/45]

= [(-54 + 40)/45]

= -14/45
