Answer:

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

8 + 9 = x, thus

x = 17
