Mr. Green and Mr. Martin played a game of marbles.
At first, the ratio of MR.Green;s to Mr. MArtins marbles was 8:3.
But then Mr.Green gave 45 of his marbles to Mr. Martin.
In the end they both had the same amount of marbles.
How many marbles did Mr.Green start with?
:
Let g = Green's marbles originally
Let m = Martin's original number
:
=
Cross multiply
8m = 3g
m = g
:
g gave 45 to m
g - 45 = m + 45
g = m + 45 + 45
g = m + 90
Replace m with g
g = g + 90
g - g = 90
g = 90
multiply both sides by 8
5g = 8(90)
5g = 720
g = 720/5
g = 144 marble, Mr Green started with

You can check this by finding m and putting it in the 1st equation
