Alright so lets break this down!

What we are looking at is:

y = 3x - 4

the question is

what is the value of x when y = 5?

This means all we have to do is plug in 5 for y and solve for x

y = 5

x = ?

therefore,

5 = 3x - 4

Now some algebra,

5 + 4 = 3x

9 = 3x

9/3 = x

3 = x

Now our concluding statement:

The value of x is 3 when y is equal to 5

Sometimes all you have to do is turn words into numbers and numbers into words!

Good luck! I hope this was helpful.
