How do you evaluate the variable expression 3a plus 2b?

Answer 1

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.

Answer 2

You need values for a and b, then you multiply a by 3, b by 2 and add your answers.
