What is the definition of a factor in algebra?

• A factor is a number or expression that divides another number or expression evenly.

• A factor is a number that is multiplied by another number to get a product.

• A factor is a term in a polynomial expression.

• A factor is a variable that represents an unknown value.

• 2

• 3

• 4

• 5

• Multiply both sides by 2, then solve for x.

• Add 4 to both sides, then divide by 2.

• Subtract 5 from both sides, then multiply by 2.

• Divide both sides by 3, then add 4.
