Find the value of x when y = 3, (y + 5) + 3y = x.

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
