Question

solve the equations x+y= 3. x-y = 1​

Answer 1

Answer:

by elimination method

x + y = 3

x - y = 1

_________

2x = 4

__________

so x = 4/2

x= 2

put value of x in any equation

2-y = 1

-y = -1

so y = 1

Answer 2

GIVEN

X + Y = 3

X - Y = 1

on adding above equation

2x = 4

X = 2

so

y = 1
