2x-4 = 20
OpenStudy (anonymous):
so 8 ... thanks (:
OpenStudy (johnweldon1993):
Not quite... 2(x - 4) = 20 Twice the difference so it would be the difference first then twice that!
OpenStudy (johnweldon1993):
If it were 8...twice the difference between 8 and 4 i 4 * 2 = 8 not 20....
OpenStudy (johnweldon1993):
2(x - 4) = 20 2x - 8 = 20 2x = 28 x = 14 Recheck....the difference 14 - 4 = 10 Twice that = 20

No answer is not 8 and even I made the mistake it is 2(x-4) = 20 as @johnweldon1993 said Sorry for the fumble
