In which question is r = -17 a solution?

devlian [24]

Answer:

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) $3-\frac{2R}{4}=10$

$-\frac{R}{2}=7$

R = -14

B) $\frac{3}{4}-2R =10$

$-2R=10-\frac{3}{4}$

R = -37/8

C) $3(R-4)=10$

$R-4=\frac{10}{3}$

$R=4+\frac{10}{3}$

R = 22/3

D) $3-\frac{R}{4}=10$

R = -28

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