Answer» Answer: Step by step EXPLANATION x + y = 20 x - y = 10 Adding both the equations above 2x = 30 x = 15 Putting the value of x in x + y = 20, we get x + y = 20 15 + y = 20 y = 5 Hence x = 15, y = 5

Answer»

Answer:

Step by step EXPLANATION

x + y = 20

x - y = 10

Adding both the equations above

2x = 30

x = 15

Putting the value of x in x + y = 20, we get

x + y = 20

15 + y = 20

y = 5

Hence x = 15, y = 5

Answer:

Step by step EXPLANATION

x + y = 20

x - y = 10

Adding both the equations above

2x = 30

x = 15

Putting the value of x in x + y = 20, we get

x + y = 20

15 + y = 20

y = 5

Hence x = 15, y = 5
