EVALUATING EXPRESSIONS #2

 

 

Directions: Evaluate the expressions below when x = -4 and y = 7. That means you should substitute a -4 in place of any xs in the expression and substitute a 7 in place of any ys. After that, follow the standard order of operations to find the value of the expression. Write that value in the space provided.

 

Examples: x + 2y 3(x + y) 6y + 2x + 3

-4 + 2(7) 3 (-4 + 7) 6(7) + 2(-4) + 3

-4 + 14 3(3) 42 + (-8) + 3
