Answer:

3/28

Step-by-step explanation:

Well basically you plug in x and c with the fractions

c= 6/7   x=3/8

-2x + c (replace the x with 3/8 and replace the c with 6/7)

and you'll will end up with..

-2*3/8 + 6/7

you then have to multiply the -2 and 3/8 (P.E.M.D.A.S)

which gives u -3/-4

you then have the equation -3/-4 + 6/7

sooo

you add it up and u get

3/28

Hope this helps! :)
