In a chess club, there are x boys and y girls. If 5 more boys and 8 more girls join, there would be half as many boys as girls. Show that y = 2x + 2
Let:x = number of boysy = number of girlstherefore 2(x+5) = (y+8)2x + 10 = y - 8y = 2x + 2
Let:x = number of boysy = number of girlstherefore 2(x+5) = (y+8)2x + 10 = y - 8y = 2x + 2
