Answer 3

To find the value of an expression when x is equal to 3, we substitute x with 3 in the given expressions:

For the expression 3x + 1: 3(3) + 1 = 9 + 1 = 10

For the expression 3 + 4x: 3 + 4(3) = 3 + 12 = 15

Therefore, the values of the expressions 3x + 1 and 3 + 4x when x is equal to 3 are 10 and 15, respectively.
