Question

x = a , y = b is the solution of the equations x-y = 2 and x+y = 4, then the values of a and b are, respectively​

Answer 1

a=3,b=1

Step-by-step explanation:

a+b=4

a-b=2

2a=6

a=3

b=1

Answer 2

Step-by-step explanation:

x=a,y=b

ADD EACH OTHER

x-y=2

x+y=4

Y WILL CANCEL

2X=6

X=3

PUTTING IN EQUATION X+Y=4

3+Y=4

Y=1

X=3=a

Y=1=b
