Suppose Alex has 3x stamps, Freddy has 5x stamps. After Freddy gives Alex 10 stamps, Alex has 3x+10 while Freddy has 5x-10
the new ratio is 7 to 9, so we have the equation: (3x+10)/(5x-10)=7/9
9(3x+10)=7(5x-10)
27x+90=35x-70
160=8x
x=20
So Alex has 3*20=60 stamps while Freddy has 5*20=100. Together they have 160
L & C represent the number of days Alfred should water the lawn and wash his car respectively.
Each time he waters, there is 59 gallons used, and each time he washes car, 28 gallons used.
59L + 28C = 175 <the aim he set for himself>
59 gallons × L will then be the total amount of water he uses for watering lawn in a week.
28 gallons × C will then be the total amount of water he uses to wash his car every week.
The expression / answer : 59L + 28C = 175
Hope this helps! :)
