Question

Find two numbers, if … c Their sum is 3/5 and their difference is 7 1/5

Answer 1

Answer:

39/10 and - 33/10.

Step-by-step explanation:

7 1/5 = 36/5  so if the 2 numbers are x and y, we have:

x + y = 3/5

x -  y =  36/5      

Adding the 2 equations to eliminate y:

2x =  39/5

x = 39/10.

So 39/10 + y = 3/5  (from the first equation).

y = 3/5 - 39/10

y = 6/10 - 39/10

y = -33/10.
