Answer:

The answer is C) 15

Step-by-step explanation:

If you replace each answer choice with the varibale, (x) then 15 would be the only choice that fits properly.

Equation:

20-x = 35-(2x)

when replacing 15 with x this is your new equation...

20-15 = 35-(2x15)

5 = 35-30

5=5

If Julie started with 20 pieces of gum and gave away x pieces. Conrad started with 35 pieces of gum and gave away twice as many pieces as Julie did. The number of  pieces of gum that Julie give away if they had the same number of  pieces of gum left is: C) 15

Julie gum=20 pieces

Conrad gum=35 pieces

Let x represent the number of pieces of gum

20-x=35-2x

Collect like terms

2x-x=35-20

Hence,

x=15

Inconclusion if Julie started with 20 pieces of gum and gave away x pieces. Conrad started with 35 pieces of gum and gave away twice as many pieces as Julie did. The number of  pieces of gum that Julie give away if they had the same number of  pieces of gum left is: C) 15
