Sallys statement is always true
for example:
-6 + 2 = -4
but if I turn it around
2 - 6 = -4
same answer
-6 -6 = -12
swap around -6 - 6 = 12
same answer
again -3 + 6 = 3
and 6 - 3 = 3

Answer:
B. (-2,3)
Step-by-step explanation:
-3x+5y = 21
x=2y-8

-3(2y-8)+5y =21
-6y+24+5y=21
-y+24=21
-y=-3
y=3
Plug-in other equation
2*3-8=x
6-8=x
x=-2
