How To Evaluate Expressions With Variables Using Order of

WebFor example, consider the expression: 3x + 5, where x is a variable. To evaluate this expression for a specific value of x, say x = 2, we substitute the value of x into the expression and perform the required operations: 3x + 5 = 3(2) + 5 = 6 + 5 = 11. Therefore, when x = 2, the value of the expression 3x + 5 is 11. 6th Grade Math Practice Problems WebTo evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.
