Question

Students were asked to explain the first step in solving the equation: 3y + 4 = 16. Susan says multiply by three. Ted says to add 4 to both sides. Nicole says subtract 4 from both sides. Brooke says to subtract 16 from both sides. Who is correct?

Answer 1

Nicole is correct

Explanation:

They need to get the 3y on one side of the equal sign and the known numbers on the other side. To do this, they must subtract the 4 from both sides.
