Gary and henry brought an equal amount of money for shopping gary spent rs 95 henry spent rs 350 after that henry had 4/7 of what gary had left. how much money did gary have after shopping

solution:

Let x = amount of money gary and henry brought for shopping

x-95=Gary's remaining money

x-350=Henry's remaining money  

(4/7)˚(x-95) = x-350

4x -380/7 = x-350

4x – 380 = 7x -2450

3x – 2070 = 0

3x = 2070

X = 690

Gary's money = 690-95=$595
