Answer:
I believe the correct answer would either be B or D.
Step-by-step explanation:
I'm not 100% certain but I have doe similar questions so I'm quite sure.
You can either multiply both equation by -2 or multiply both equations by 3 because when you multiply -2 you can eliminate x term
1. -2(x) -2(y) = -2(1) -> -2x -2y=-2
So far
-2x-2y=-2
+
2x-3y= -30
(-2x+2x) + (-2y-3y)= -32
0-5y = -32
Y= 32/5
Substitute y with 32/5
X+ 32/5= 1
Minus -32/5 over
X= -27/5
I don’t know why my answer doesn’t match with those answers above. I also checked by calculator. Did you write the question wrong?
Answer:
13c + 9d
Step-by-step explanation:
X+y and y+x are the same as stated by the commutative law.
This is because let’s say x=2 and y=3,
2+3=5 and 3+2=5
8 hundred thousands and 1 thousand.
