The worksheet requires students to evaluate twenty distinct algebraic expressions involving two variables, specifically defined as x = 5 and y = 4. By applying substitution and basic arithmetic operations, students can test their proficiency in handling exponents, order of operations, and multi-variable equations. A complete answer key is included at the end to allow for self-assessment and verification of accuracy.","Algebraic expressions (2 variables)   \nGrade 5 Pre-Algebra Worksheet  \nEvaluate the following expressions for x = 5 and y = 4.  \n1. x + y   11. y3  \n_______  \n2  \n2. 2y²   12.
