Glass = x 

Burger = y

French fries = z 


1st Equation

x+x+x=30

Step 1: Simplify both sides of the equation.

x+x+x=30

(x+x+x)=30(Combine Like Terms)

3x=30

3x=30

Step 2: Divide both sides by 3.

 \frac{3x}{3}  \frac{30}{3}


x=10

Second Equation ↓


10+ y + y = 20

(y+y)+(10)=20(Combine Like Terms)

2y+10=20

2y+10=20

Step 2: Subtract 10 from both sides.

2y+10−10=20−10

2y=10

Step 3: Divide both sides by 2.

 \frac{2y}{2} = \frac{10}{2}

y = 5


Third Equation

5 + 2z + 2z = 9 

Step 1: Simplify both sides of the equation.

5+2z+2z=9

(2z+2z)+(5)=9 (Combine Like Terms)

4z+5=9

4z+5=9

Step 2: Subtract 5 from both sides.

4z+5−5=9−5

4z=4


Step 3: Divide both sides by 4.

 \frac{4z}{4}  \frac{4}{4}

z=1


Fourth Equation 


x = 10

y = 5 

z = 1 


5 + 1 
× 10 

5 + 10 

15 


Hence the answer of the riddle is = 15 



Hope it helps ! :)

PrincessNumera: Yup ! that what's i said in comments up
ishanaghosh: 5+z+z=9 and not 2z
ishanaghosh: Why did you put 2
ishanaghosh: For 2 fries, two z are to be put. Not two 2z
PrincessNumera: See there is 2 packets in one number see carefully again the pic @
PrincessNumera: 5 + 2z +2z becoz there are 2 packets in one variable so 2z
ishanaghosh: Oh. I think I missed that. I am sorry.
PrincessNumera: No problem ^^
ishanaghosh: Hope you dont mind that my eyes failed me.
PrincessNumera: Mistakes happen with every person :)
