Im Not That sure But I Belive That If Denominators Are The Same Keep It And Just Do The Math In The Numerator's . ( For Adding ) But Multiplying You Do Both and If The Numerator Is The Bigger Than The Denominator Your Going To Have To Do Extra Math Like A Common Denominator ( I Belive ) .

Tameka bought 50 cans of soda ( cola, grape, and orange) to serve at a party. She has 8 more colas than grape sodas, and 3 less
Gwar [14]

Answer:

Orange = 12

Grape = 15

Cola = 23

Step-by-step explanation:

Turning this into equations you can give each soda a variable

Cola = C | Grape = G | Orange = R

Then you get:

8 + G = C

R + 3 = G

C + G + R = 50

We want to get a variable all by itself in an equation so first I'm going to put the second equation (R + 3 = G) in the first (8 + G = C) by replacing the G to get

8 + (R + 3) = C  Combine the variables 11 + R = C and put that new equation into the last equation

(11 + R) + G + R = 50    

Now plug our original second equation (R + 3 = G) into our third to get

(11 + R) + (R + 3) + R = 50    

Combine and get

14 + 3R = 50      Subtract over the 14

3R = 36              Divide by 3

Orange Sodas = 12

Our new 3rd Equation is now:   C + G + 12 = 50, subtract over 12 to get

C + G = 38

Plug either equation 1 or 2 into that one, I'll do 1

(8 + G) + G = 38

8 + 2G = 38

2G = 30

Grape Sodas = 15

Now our 3rd equation is C + 15 = 38, subtract over 15

Cola Sodas = 23

Orange = 12

Grape = 15

Cola = 23

12 + 15 + 23 = 50
