If I give my brother 5 dollars, then we will have the same amount of money. If instead he gives me 25 dollars, then I'll have twice as much money as he will have. How much money does my brother currently have (in dollars)?

y = your money

b = brother money

y-5 = b+5 <======given

2(b-25) = y+25 <======given Sollve the sytem of equations....looking for b

Re-arange the first equation

y = b+10 sub this into the second equation.....

2(b-25) = ( b+10) + 25

** b =** 10 + 25 + 50 = __ 85 dollars__ ( and you have 95)

You have Dollar 15 and Your Brother have Dollar 20

If 5 give to you

15 + 5 = 20 = 20

If 25 give to you

15 + 25 = 40 = 2*20

If Brother has 20 and you have 15 ....

when you give him 5 he has 25 and you have 10 ....not the same amount......do you see?
