Answer 2

Answer:

please mark as brainliest

Step-by-step explanation:

Given -

x+y=7 ----------------(1)

x−y=−3----------------(2)

Solve the first equation for y

y = 7-x#

Substitute this value in equation(2)

x−(7−x)=−3

x−7+x=−3

2x=−3+7

2x=4

x=42=2

Substitute x=2 in equation (1)

2+y=7

y=7−2

y=5
