12x + 6 when x = 2 1/4 is

12(2.25) + 6 =

27 + 6 =

33.

It is: 12*(2.25) + 6 = 33

12x + 6 = 33 (if x = 2 and 1/4)

12x + 6 = 33 (if x = 2 1/4)

Option 1 — x = 2¼ (mixed number)

Plug in x = 2¼:

= 12(2¼) + 6

= 12(2 + ¼) + 6

= 24 + 3 + 6

= 33

Option 2 —you want two answer, one for x = 2 and another for x = ¼:

Plug in x = 2:

= 12(2) + 6

= 24 + 6

= 30

Plug in x = ¼:

= 12(¼) + 6

= 3 + 6

= 9

If you want one answer for x = 2¼

x = 2¼ --> 12x + 6 = 33

If you want two answers (one for x = 2 and another for x = ¼)

x = 2 --> 12x + 6 = 30

x = ¼ --> 12x + 6 = 9

For x = 2, just plug in two where x is:

12(2) + 6

24 + 6

30

________________________

For x = 1/4 , just plug in one-fourth where x is:

12(1/4) + 6

Recall that whole numbers multiply into the numerator when being multiplied to a fraction. Keeping this in mind, finish up the process:

12/4 + 6

Four goes into twelve three times, so this will become:

3 + 6

9

x = 2 1/4

12(2 1/4) + 6 = (24 + 3) + 6 = 33

I don't believe he meant it as a mixed fraction. I think he wanted two separate instances of substitution. However, Cutler if you're reading this and you actually meant to write x = 2¼ then this is your answer instead. I doubt that's what you intended to write though.
