Step-by-step explanation:
We are given system of equations as
X plus Y equals negative 3
so,
X minus Y equals one
so,
so, system of equations are
now, we can solve it
we can add both equations
now, we can solve for x
now, we can find y
so, solution is
now, we can draw graph
and then we can find intersection point
that is (-1,-2)
so, x=-1 and y=-2
which is same
so, Zach is right about solution
