    x = 17

    Step-by-step explanation:

    Given

    (y + 5) + 3y = x ← substitute y = 3

    (3 + 5) + 3 (3) = x, that is

    8 + 9 = x, thus

    x = 17

    x=17

    Step-by-step explanation:

    This question is just like substitution, that is a number will be given to substitute a letter ...

    Ok let's start with the question

    (y+5) + 3y=x

    And we are to determine the value of x when y is 3 ...

    That means we will replace any where we see y with 3

    (3+5) + 3 (3) = x

    8+9=x

    x=17

    Therefore when y is 3, x is 17

    Our final answer is 17
