When simplifying the equation 5a - 3a - 8 + 1 = -19, what is the result of combining like terms?

• 8a - 7 = -19

• 5a - 7 = -19

• 2a - 7 = -19

• 2a + 7 = -19

What is the next step after combining like terms in the equation 5a - 3a - 8 + 1 = -19?

• Add 7 to both sides

• Subtract 7 from both sides

• Divide both sides by 2

• Multiply both sides by 2

In the equation -4p - 2p + 5 = 3p - 8p + 6, what is the result of combining like terms?

• -6p + 5 = 5p + 6

• -6p + 5 = -5p + 6

• -6p + 5 = -5p - 6

• -6p - 5 = -5p + 6

What should you do if you have variables on both sides of an equation?

• Move all constants to one side

• Move all variables to one side

• Add the variables together

• Divide both sides by the variable
