Question

If x=a,y=b is the salution of the Equation
x-y=2 and x+y4 then the value of a and b is​

Answer 1

       $\underline{\bold{Solution:}}$

       $\text{The two given equations are:}$

       $x - y = 2 \text{ ------ (i)}$

       $x + y = 4 \text{ ------ (ii)}$

       $\text{Adding (i) and (ii)}$

$\implies x-y + x +y = 2 + 4$

$\implies 2x = 6$

$\implies \boxed{x =a = 3}$

       $\text{Substracting (i) and (ii)}$

$\implies x - y - (x + y) = 2 - 4$

$\implies x - y - x - y = -2$

$\implies -2y = -2$

$\implies \boxed{y = b=1}$
