“Use the properties to rewrite this expression with the fewest terms possible: 2 - 4x + 3(y – 4) + 10”

- 4x + 3y

Step-by-step explanation:

Distribute the 3 to the expression inside the parenthesis.

2 - 4x + 3 (y - 4) + 10

2 - 4x + 3y - 12 + 10

Bring the - 12 + 10 next to the 2 at the beginning of the expression.

2 - 12 + 10 - 4x + 3y

Add or subtract like terms (2 - 12 + 10 should cancel out).

0 - 4x + 3y

- 4x + 3y

based on context clues you gave i'm assuming the answer would be c.
