Answer:
x>125
Step-by-step explanation:
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.
If 7x+3=24, that means x would be 3 so if you take 5-4x then that would be -7.
