Question

If x= a and y=bis solution for
S solution for the pair of equations x - y = 2 and x + y = 4, then find the values of a and b.​

Answer 1

let x-y=2 ........equation..1st

x+y=4......equation....2nd

now....adding equation 1st.and 2nd..we get

x=3

then put the value of x in equation 1st..we get

y=1

now x=a=3

y=b=1
