In the equation x + 5(3x - 4) = 12x + 4, what do you get after distributing 5?

• 15x - 20

• 3x - 4

• 5x - 20

• 15x + 20

After combining like terms in the equation x + 15x - 20 = 12x + 4, what is the resulting equation?

• x + 15x - 20 = 4

• 16x - 20 = 12x + 4

• x + 15x = 12x + 4

• 16x - 20 = 4

What is the next step after getting 4x - 20 = 4 in the equation?

• Subtract 4 from both sides

• Add 20 to both sides

• Combine like terms

• Use the distributive property
