Now your equation looks like this: 5x/3 =x/9 - 6/7 after you combine the -2/7 and -4/7.
Do you agree?
OpenStudy (anonymous):
Yes:)
OpenStudy (radar):
Now subtract x/9 from both sides of the equal sign getting:
5x/3 - x/9 =-6/7 did you follow that little maneuver?
OpenStudy (anonymous):
Yes i think so
OpenStudy (radar):
O.K Now multiply all terms by 9 getting
15x-x=-54/7 combine the similar terms on the left.
14x=-54/7
