Question

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

Answer 1

None

Explanation:

For option A

3-2r/4=10 and combining like terms and re-arranging we obtain

-2r/4=10-3

-2r/4=7

r=7*4/-2=-14

For option B

3/4-2r=10 then combining like terms and re-arranging

-2r=10-3/4

-2r=9 1/4

r=(9 1/4)/-2=-4.625

For option C

3(r-4)=10 dividing both sides by three first

r-4=10/3

r=10/3+4= 7 1/3

For option D

3-r/4=10

-r/4=10-3

-r/4=7

r=7*-4=-28

Therefore, none of the options yields r=-17
