the sum of two different numbers x and y is 70 and the differences when the smaller number is subtracted from the larger number is 30 what is the value of xy

1000

Step-by-step explanation:

Lets just say x is the bigger number. We can create two equations.

x + y = 70

x - y = 30

If we add these equations together, we get that:

2x = 100

and that

x=50

Plugging x back into any of the equations gets us that y = 20, so xy = 20*50 = 1000
