If I give my brother 5 dollars, then we will have the same amount of money. If instead he gives me 24 dollars, then I'll have twice as much money as he will have. How much money does my brother currently have (in dollars)?

Lets use x and y, x being your money and y being your brothers

 

 

(If I give my brother 5 dollars, then we will have the same amount of money.)

that means that x-5=y+5; x= y+10

 

( If instead he gives me 24 dollars, then I'll have twice as much money as he will have.)

 

using this information we can write the amount of money as 2(y-24)=x+24

 

(substitue y) 2(y-24)=y+34 =   2y-48=y+34 =  y=82

 

Since y stands for your brothers money that means your brother has 82 dollars and you have 92. Hope this helps! :)
