HURRY PLS!!!!
Tony solves the linear equation
3(x - 3) + 2x + 9 = 2x + 2(x - 1)

using the step shown below.

Step 1: 3x - 3 + 2x + 9 = 2x + 2x - 1

Step 2: 5x + 6 = 4x - 1

Step 3: 5x - 4x = -1 - 6

Step 4: x= -7

a. He incorrectly applied the multiplication and division properties of equality.

b. He distributed incorrectly.

X c. He incorrectly combined like terms.
