So x and y sum means add difference means subtract so we have x+y=55 times (x-y) use distributiver property which is a(b-c)=ab-ac so distribute 55(x-y) 55(x-y)=55x-55y
so we have x+y=55x-55y add 55y to boh sides x+56y=55x subtract x from both sides 56y=54x divide both sides by 2 28y=27x to find the ratio, switch the numbers around ratio of y:x=27:28 therefor x is the greater number ratio of larger to smaler is 28:27
Deandre = x Kala = x + 6 Eric = 3(x+6) x + x + 6 + 3(x+6) = 119 2x + 6 + 3x + 18 = 119 5x + 24 = 119 5x = 95, x = 19 Deandre has $19 Kala has 19 + 6 = $25 Eric has 3(25) = $75
