Question

If we have two variables x and y when x=a and y=b is the solution of equations x-y=2 and x+y=4, then what will be the value of a and b

Answer 1

Answer:

a=3 b=1

Explanation:

if x=a and y=b

a-b=2 & a+b=4

Adding both equations

a-b+a+b=6 2a=6 a=3

if a=3 then

a-b=2 3-b=2 b=1

Answer 2

Answer:

answer is = ,a= 3,,b=1......
