Question

How can you evaluate an algebraic expression

Answer 1

Replace letters with value assigned to it, solve using order of operations.

Answer 2

Explanation:

In algebra we work with variables and numerals. To evaluate an algebraic expression simply means that you are going to determine the value of an expression by substituting and evaluating using the operation order.

in summary in order to evaluate an algebraic expression

• you must identify the variable and its value
• you will substitute the given value for the variable
• complete the necessary calculations

Take for example;

evaluate 2a + 4b - 2c

given that a = 2 , b = 1 , c = 5

since you already know the value of the variables you substitute them into the question

we have

2(2) + 4(1) +2 ( 5)

4 + 4 + 10
