    It is simple
    Step 1) substitute x = 5 into the equation
    3x +4
    3(5) + 4 gives you 3 times 5 + 4
    The answer is 15 + 4 which is 19

    Now substitute a and b into the equation 3(a) + 4(b) when the a = 6 and b = 5
    Hereby 3(6) + 4(5)
    3 * 6 = 18 and 4* 5 = 20
    18 + 20 = 38
    The answer is 38

    Now finally
    Substitute a and b Into the equation
    3(3) + 4(6)
    9+ 24 = 33
