x - 1/7 = 3 4/7 what is 1/7 + 4/7?

OpenStudy (isaiah.feynman):

Cool. Let the brains duel it out!

OpenStudy (anonymous):

(7x - 1) / 7 = 25/7 Now both side denominators are same which can be eliminated 7x - 1 = 25 7x = 26 x = 26/7

OpenStudy (shamil98):

you don't need to do all of that ganibl

OpenStudy (shamil98):

x - 1/7 = 3 (4/7) x = 3(4/7) + 1/7 x = 3(5/7) x = 26/7
