There are four sets of evaluate algebraic expressions worksheets:
Examples, solutions, videos, and worksheets to help Grade 7 and Grade 8 students learn how to evaluate expressions with variables (substitute positives numbers).
There are two sets of Evaluating Expressions with Variables worksheets.
These are the steps to evaluate expressions with variables:
Evaluate the expression 3(x + 1)2 + 5(y + 2) when x = 2 and y = 4.
Substitute x with 2 and y with 4: 3(2 + 1)2 + 5(4 + 2)
Evaluate expressions within parentheses: 3(3)2 + 5(6)
Compute the exponents: 3(9) + 5(6)
Multiply and Add: 27 + 30 = 57
Remember to follow the order of operations and simplify each step along the way to evaluate the algebraic expressions accurately.
