Answer 2

Answer:

sum of two numbers

x+y=138••••••••••••(1)

difference between two numbers

x-y=88••••••••••••(2)

Step-by-step explanation:

by adding (1) & (2), we get

x+y+x-y=138+88

2x=226

x=226/2

x = 113

put x=113 in equation (1)

x+y=138

113+y=138

y=138-113

y=25

Values of x and y are

x=113, y=25

Check:-

put x=113, y=25 in equation (2)

x-y=88

113-25=88

88=88
