What is the first step in solving the equation 2x + 1 = -3x + 6?

• Add 3x to both sides

• Add 1 to both sides

• Subtract 1 from both sides

• Subtract 3x from both sides

After moving the constants to one side, what is the resulting equation?

• 2x = -3x + 5

• 2x + 1 = 5

• 2x = -3x + 6

• 2x = 5

What is the value of x after solving the equation 2x + 1 = -3x + 6?

• x = 1

• x = 3

• x = 2

• x = 0

What is the next step after finding the value of x?

• Find the value of y

• Verify the value of x

• Check for errors

• Graph the equations
