Evaluate algebraic expressions quick check
To evaluate an algebraic expression, you substitute the given values for the variables and perform the arithmetic operations.
For example, consider the expression "3x + 2y" when x = 4 and y = 5. To evaluate the expression, you substitute x = 4 and y = 5:
3(4) + 2(5)
Now, you perform the arithmetic operations:
12 + 10 = 22
Therefore, when x = 4 and y = 5, the value of the expression "3x + 2y" is 22.
