everywhere you see the variable, put it's value there instead, then do all of the math (+-x/)
To "evaluate" an expression, you need to know the value for the variables.
It means to substitute a number values into an expression.
You substitute the variable for its value. Or you substitute the variables for each of the values.

Replace all the variables in the expression by their numerical values and calculate the result.

To evaluate means to find the value. Substitute the values of the variables and calculate the value. [You may need to solve for the values of the variables first.]
You replace each variable by its value. Then you do the indicated calculations.
Take 3 and substitute into the expression given to you but not mentioned in the question here and evaluate the expression. "Sub and Solve" I say.
Replace each variables in the algebraic expression by its [known] value and calculate the value (ie evaluate) of the algebraic expression.
The evaluate a algebraic math expression you first must substitute a number for each variable. Then you must perform the operation in the correct order.
It is evaluating the expression.
