Answer:
xy = -2
Step-by-step explanation:
To solve:
5 + 14xy = 9xy - 5
=> First subtract 9xy from each side of "="
5 + 5xy = -5
=> Now, subtract 5 from each side:
5xy = -10
=> Finally divide 5 on each side:
xy = -10/5
xy = -2

456.98-10-14.95-6.07-109.10-30=<span>286.86
So her new </span>checkbook balance is $286.86
C=x+9, c+x=99, c=99-x
So we have two equations equal to c, c=x+9 and c=99-x, since c=c:
x+9=99-x
2x+9=99
2x=90
x=45, and since c=x+9, c=54
So Charlie weighs 54 kg and his brother weighs 45 kg.
