EVALUATING EXPRESSIONS #1

Directions:  Evaluate the expressions below when x = 4 and y = 7.  That means you should substitute a 4 in place of any x’s in the expression and substitute a 7 in place of any y’s.  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(11)			42 – 8 - 3
	              18				   33			     31
