X=3 y=-2
4x - 6y
4(3) - 6(-2)
12 - (-12) (two negatives cancel out)
12 + 12 = 24
answer: 24
What you do is add up the coins in two piles
1. all the coins added up
2.coins that are more than 10 cents (or equal)
take number 2 and put that in the numerator (top spot on a fraction)
and take number 1 and put it on the denominator (bottom spot on a fraction)
then simplify it if needed.
50/224 is the raw data simplify it for the real answer
25/112 is the simplest you can do so there's your answer. hope this helped :)
<span>a=7b+8c+9d-10
8c = a - 7b - 9d + 10
c = (</span>a - 7b - 9d + 10) / 8
It is infinitely many solutions I hope this helps
