isohedron has positive numbers only
numeric expressions apply operations to numbers. for example, 2(3 + 8) is a numeric expression. algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division). for example, 2(x + 8y) is an algebraic expression.
simplify the algebraic expression:
then evaluate the simplified expression for x = 3 and y = -2.
to solve, simplify the algebraic expression using the basic properties of real numbers
now replace x with 3 and y with -2 in the simplified expression.
