the first one?

OpenStudy (anonymous):

yep

OpenStudy (anonymous):

Okay, our first step is to multiply 7 to both sides, what's 18 * 7?

OpenStudy (anonymous):

126

Yes, so we have: \(9x = 126\) Now divide 9 to both sides, what's 126 / 9?

OpenStudy (anonymous):

14

OpenStudy (anonymous):

Yes, that's our answer.
