Respuesta :
x+y=-11, y= -11 -x
x-y=41
---------
2x = 41 - 11 = 30
x=30:2
x=15
y= -11-x
y=-11-15
y= -26
x-y=41
---------
2x = 41 - 11 = 30
x=30:2
x=15
y= -11-x
y=-11-15
y= -26
x+y=-11 x-y=41 equations for the two number
x=-11-y (-11-y)-y=41 separate x, then plug it into the other equation
-y-y=41+11 solve for y
-2y=52
y=-26 x=-11-(-26) plug y into the equation for x
x=15
x=-11-y (-11-y)-y=41 separate x, then plug it into the other equation
-y-y=41+11 solve for y
-2y=52
y=-26 x=-11-(-26) plug y into the equation for x
x=15
