To see how they are related, let us solve the two equations.
FIRST EQUATION



SECOND EQUATION



Hence the solutions to the two equations are ADDITIVE INVERSE of each other.
51*11=561 615-561=54 54/6=9
They sold 9 discounted pizzas.
P-24=15
because if argentina has 15 more than south africa then you need to subtract 24-15=p which is pretty much the same things as p-24=15
and if you need to know how many provinces south africa has then 9 provinces should be your answer
Answer:
the slope is 0
Step-by-step explanation:
You first do -9--9 and then divide 14-8
