w many pieces of gum did sophie gave away if they had the same number of pieces of gum left
1 answer:
Answer:
x = 50
Step-by-step explanation:
Pieces of gum given by Sophia = x
Pieces of gum left with Sophia after giving x pieces = 25 - x
Pieces of gum given by Maria = 2 × Gums given by Sophia = 2x
Pieces of gum left with Maria after giving 2x pieces = 75 - 2x
Pieces of gum left with Sophia = Pieces of gum left with Maria
25 - x = 75 - 2x
2x - x = 75 - 25
x = 50
Pieces of gum left with Sophia is 50.
