Finding Value of an Expression
Finding Value of an Expression
Value of an Algebraic Expression By assigning values to variables in an algebraic expression, we can find the value of the expression. From the following examples, we can learn How to Find The Value of an Algebraic Expression. Illustration 1: Find the value of algebraic expression (p + q + r), if p = 1, q = 2 and r = 3 Solution: The given algebraic expression is (p + q + r). Substitute the respective values of p,q and r in the algebraic expression, and we get = 1 + 2 + 3 = 6 So The Value of the Given Algebraic Expression (p + q + r) is 6.
Illustration 2: Find the value of algebraic expression (7x - 3y + 4), If x = 2 and y = 3
