Answer:
B.
Step-by-step explanation:
Since 21 is divided by 3 you might think that it is equivalent but remeber you have to divide by both sides, so if you divide 21 by 7 it works but 28 by seven does not! Hope this helps!
3+8x-2y-x+1+4y
Combine all like terms and
7x+4+2y is your answer
Answer:
24
Step-by-step explanation:
First do parenthesis:

Then do multiplication:
3*(10)-6 -> (30)-6
Then complete it with subtraction:
(30)-6 -> (24)
So your answer would be 24!
