To evaluate the variable expression 3a + 2b, you need specific values for the variables a and b. Once you have those values, you substitute them into the expression and perform the arithmetic operations. For example, if a = 4 and b = 5, then 3(4) + 2(5) = 12 + 10 = 22. This gives you the final value of the expression.
