Brian had 6 times as much money as Rahim. Brian spent $287 of his money to buy a birthday gift for his grandma while Rahim was awarded $73 for winning a competition. In the end, they had the same amount of money. How much did they have altogether at first?

Brian had 6 times the money Rahim did:

 

B=6*R

 

Brian lost 287 dollars, and Rahim gained 73, leaving them at the same amount of money.

 

B-287=R+73

B= R+360

 

We can equate these two equations

 

R+360=6R

360=5R

R=72

 

If Rahim had $72, then Brian had 6 times this amount

 

72*6=432

 

Thus, their combined amount at the start is given by

 

72+432=504

 

They had $504 together to start with. Hope this helps!
