In which question is r = -17 a solution?
a) 3 - 2r/4 = 10
b) 3/4 - 2r = 10
c) 3(r - 4) = 10
d) 3 - r/4= 10

None

Step-by-step explanation:

Simply solve each linear equation and get value of R.

Or another way can be to put value of R in all four options and find whether left hand side is equal to right hand side or not.

A)

   R = -14

B)  

    R = -37/8

C)  

  R = 22/3

D)

    R = -28

So, none of the option's are having solution R =-17.
