What is the equation set up to find when Arman will be three times older than Dia?

• 18 + 3y = 2 + y

• 18 + y = 2 + 3y

• 18 + y = 3(2 + y)

• 18 + 2y = 3(2 + y)

What is the first step in solving the equation 18 + y = 3(2 + y)?

• Divide both sides by 3

• Add y to both sides

• Subtract y from both sides

• Distribute 3 on the right side
