Equivalent Equations

Which equation is equivalent to  3[7x - 4(x - 3)] + 1 = 16?
A.)  9x - 2 = 16
B.)  9x + 37 = 16
C.)  17x - 2 = 16
D.)  17x + 13 = 16

---

3[7x - 4(x - 3)] + 1 = 16
3(7x - 4x + 12) + 1 = 16   {used distributive property with -4}
3(3x + 12) + 1 = 16   {combined like terms}
9x + 36 + 1 = 16   {used distributive property with 3}
9x + 37 = 16   {combined like terms}

B.)  9x + 37 = 16
