Pls help. The qn is from P6 Essential - advance model drawing - Let’s Learn section

I don’t understand the solution given specifically the part on “3/3J= 12u + 315”
(Where did the 12u come from? )

Jessie has $315 more than David. When Jessie spent 1/3 of her money and David spent 0.25 of his money, they had $1740 left altogether. How much money did they have altogether at first?
