Write an equation and solve for x: Three more than twice x when x=9

Question

1. Write the equation
2. Solve the equation

My answer:
2x + 3 = 9
Would this answer be correct?

Answer 1

Would my answer be this instead:
2x + 3=21

Answer 2

2x + 3

x = 9 (given in the problem)

2(9) + 3 = 21

Answer 3

Yay so I got my second answer right then.

2x + 3=21
Because x=9
