Isolate x. Add 7x to both sides.
OpenStudy (anonymous):
why not 4
OpenStudy (ranga):
You can do that too. With 4x you have to subtract it from both sides. With 7x you can dd to both sides.
OpenStudy (anonymous):

OpenStudy (ranga):

5 + 5/8 = (40 + 5)/8 = 45/8
OpenStudy (anonymous):
i got 45/88
OpenStudy (anonymous):

OpenStudy (ranga):
Yes. But it should be x < 45/88
