MULTIPLE CHOICE QUESTION

Evelyn, Aria, and Scarlett are on a treasure hunt. They find a chest locked with a puzzle that says, 'Solve for x: 5x = 25' to open. Can you help them unlock the treasure?

x = 10

x = 3

x = 2

x = 5

Answer explanation

To solve for x, divide both sides by 5: x = 25 / 5 = 5. Therefore, x = 5 is the correct answer choice.
