Just Put x=3/2 in the equation

4 1/2?

4. cbrennan123

you put 2(3/2) which is 3 and the you do 3+1. I hoped that helped

I think you are confused let me show you with latex. $\left| 2x+1 \right|$$\left| 2(\frac{ 3 }{ 2 })+1 \right|$$\left| \cancel 2\ (\frac{ 3 }{ \cancel 2 })+1 \right|$ $\left| 3+1 \right|$$\left| 4 \right|$ or 4

@misswiss123 got it ?

12. misswiss123

Oh I had put 4 1/2 so it would just be 4 right?

13. hba

Yeah right :)
