Answer:
Step-by-step explanation:
When multiplying or dividing two negatives, multiply or divide the normal way and make your answer positive. Two negatives make a positive.
Answer is C. Definitely not d right off the bat because both exponents are negative so cross that out. After that its just counting zeros.
X+y=2 (label equation one)
x-y=4 (label equation two)
y=-x+2 (equation one rearranged, label this equation equation three)
sub 3 into 2
x-(-x+2)=4
x+x-2=4
2x-2=4
2x=6
x=3
sub x=3 into equation one
3+y=2
y=-1
therefore x=3 and y=-1
