I'm having some trouble with the following task. I've been calculating back and forth on the following equations without getting anywhere.
Sarah is 12 years older than Reed, in 5 years time Sarah is twice the age of Reed 4 years ago, how old are they now?
$Sarah = Reed + 12$
$2(Sarah +5) = Reed -4$
This should be simple enough, still I can't get it. Maybe the calculations I've been doing on these numbers, tried lots of pages, are wrong or the equation is wrong to begin with. Any pointers would be really appreciated.
