Answer:
x=-1, y=-3. (-1, -3).
Step-by-step explanation:
x+y=-4
3x-6y=15
---------------
x=-4-y
3(-4-y)-6y=15
-12-3y-6y=15
-12-9y=15
9y=-12-15
9y=-27
y=-27/9
y=-3
x+(-3)=-4
x-3=-4
x=-4+3
x=-1
Answer:
see below
Step-by-step explanation:
y = 5x-3
Let x = -2 y = 5(-2) -3 = -10 -3= -13
Let x = -1 y = 5(-1) -3 = -5-3 = -8
Let x = 0 y = 5(0) -3 = 0-3 = -3
Let x = 1 y = 5(1) -3 = 5-3 = 2
Let x = 2 y = 5(2) -3 =10-3 = 7
