Does, this make any sense to anyone? I honestly don't understand it. I'm learning functions by the way.

    t = 7

Explanation:

If we replace every copy of x with t, then we go from this

F(x) = 3x+5

to this

F(t) = 3t + 5

All we've done really is change the letter. We still are dealing with a variable. We're told that F(t) is equal to 26, which would allow us to replace the "F(t)" with "26" in the second equation above.

So we now have the equation 26 = 3t+5 which is the same as 3t+5 = 26

Let's solve for t

3t+5 = 26

3t = 26-5 subtract 5 from both sides

3t = 21

t = 21/3 divide both sides by 3

t = 7  is the answer

Now note that...

F(t) = 3t + 5

F(7) = 3*7 + 5 replace t with 7

F(7) = 21 + 5

F(7) = 26

This means we got F(t) = 26 when t = 7

It's the same as saying x = 7 leads to F(x) = 26.

This helps confirm we have the correct answer.

t = 7

You need to do 743-27-25-5=? after you subtract all deductions then you divide it by two and you should get the right answer but if it you get the right answer from subtracting then you need to stop and choose the right answer
