Simplify 3/4 - 4r + 1/2r - 1/2+ 1/2r

-3r+1/4

Step-by-step explanation:

3/4-4r+1/2r-1 x 1/2+1/2 x r

3/4-4r+1r/2-1x1/2+1/2 x r

3/4-4r+ 1r/2-1x1/2+1/2 x r

3/4-4r+ r/2-1 x 1/2 +1/2 x r

3/4-4r+r/2-1 x 1/2+1/2 x r

3/4-4r+r/2-1/2+1/2 x r

3/4-4r+r/2-1/2+1/2r

3/4-4r+r/2-1/2+1r/2

3/4-4r+r/2-1/2+1r/2

3/4-4r+r/2+r/2

3/4-4r+r/2-1/2+r/2

1/4-4r+r/2+r/2

1/4-4r+ 2xr/2        (two times r/2 equals r)

1/4-4r+r

1/4-4+r

1/4-3r

1/4-3r

-3r+1/4

-3r+1/4

and that's how you get your answer.

i hope this helps.
