What is the next step after combining like terms in the equation -9 - 3x = 2x + 11?

• Divide by 5

• Multiply by 2

• Subtract 11 from both sides

• Add 3x to both sides

What is the least common denominator for the fractions 1, 4, and 3?

• 6

• 16

• 8

• 12

What do you get when you multiply the entire equation by the least common denominator?

• 12x = 3x - 1 - 4

• 12x = 3x + 4 - 1

• 12x = 3x + 1 - 4

• 12x = 3x + 1 + 4

What is the simplified form of 12(x + 1)/4?

• 6(x + 1)

• 3(x + 1)

• 4(x + 1)

• 12(x + 1)

What is the result of combining like terms in the equation 12x = 3x + 3 - 4?

• 12x = 3x + 1

• 12x = 3x - 7

• 12x = 3x - 1

• 12x = 3x + 7

What is the value of x in the equation 9x = -1?

• x = -9

• x = -1/9
