J + M = 32
J = 3M
4M = 32
M = 8
Mark has 8 Marbles, John has 24
Of course you didn't NEED algebra for this, I was just showing off :)
Between them, John and Mark have 32 marbles. John has 3 times as many as Mark. How many marbles does each boy have?
Does it count if I know of someone who's missing a few marbles ?
Less than John
32/4 = 8
John = 8 x 3 = 24
Mark = 8 x 1 = 8
Check it: 24 + 8 = 32
