Answer:
x=7/2 y=3/2
Step-by-step explanation:
x+y=5
x-y=2 (by substitution method)
2x=7
x=7/2
7/2+y=5
y=5-7/2
=10-7/2
y=3/2

Hi
Here’s the answer
Hope it is helpful
Mark me brainliest
First suppose
x + y=5. - equ 1
x - y=2. - equ 2
Adding equations 1&2
x + y= 5
+. x - y = 2
Answer:2x=7
x=7/2
Putting x=7/2 in equation 1
x + y = 5
7/2 + y=5
y =5-7/2
y=5/1-7/2
y=5 x 2/1 x 2 - 7/2
y= 10/2-7/2
y=10-7/2
y=3/2
Solution: (x,y)=(7/2,3/2)
OR
(x,y)=(3.5,1.5)

Answer:2x=7
x=7/2
Putting x=7/2 in equation 1
x + y = 5
7/2 + y=5
y =5-7/2
y=5/1-7/2
y=5 x 2/1 x 2 - 7/2
y= 10/2-7/2
y=10-7/2
y=3/2
Solution: (x,y)=(7/2,3/2)
OR
