The product of 9 and a number is 12 less than three times that number. What is the number?

HanAkoSolo (jamierox4ev3r):

product : multiplication is : equal sign 9 x n = 3n-12 ^ do you see how i got there? to simplify: 9n=3n-12

OpenStudy (anonymous):

no

HanAkoSolo (jamierox4ev3r):

you just interpret the words and turn it into an equation

OpenStudy (anonymous):

so theanswer is 9

HanAkoSolo (jamierox4ev3r):

no, you need to solve 9n=3n-12 9n=3n-12 -3n -3n -------- 6n=-12 n=-2

OpenStudy (anonymous):

-6

HanAkoSolo (jamierox4ev3r):

no, -2 :)

HanAkoSolo (jamierox4ev3r):
