The answer is the last equation D.

anonymous · Answer

Since Molly is twice and plus 5 years older than Jacob 
J=2m+5

anonymous · Answer

Oh wait never mind I did the equation wrong

anonymous · Answer

It's A sorry I read It incorrectly

anonymous · Answer

Since j=2m+5 
And you're looking for Molly's age you try to get m by itself
Subtract 5 to both sides 
J-5=2m 
Divide 2 to get m by itself 
1/2j-5/2=m
