    x+y=2-------------1) x-y=-2 ------------2) solving for x in 1st equation : x+y=2 x=2-y now put this value in 2nd equation x-y=-2 2-y-y=-2 2-2y=-2 -2y=-4 y=\(\frac{-4}{-2}\) y=2 x = 2-y = 2-2=0

    you should add both equations as one y is wth postv sign nd othr is wth negtv sign so they will cancel each other nd both x have postv sign so the will be addes nd their sum will 2x nd right side of equation again 2 is wth pstv nd ngtv sign so they will cancl each othr nd x will b equal to 0
