when you solve can you please show the work, please? x-.30x=28

OpenStudy (anonymous):

combine like terms, so it becomes .70x=28 then divide by .7 both sides and you get answer, i think 40 or 400, dont have calculator on me

OpenStudy (anonymous):

how did you get .70

OpenStudy (anonymous):

by combining, the implied 1 on the 1st x and the -.30x next to it, they are like terms making .70x

OpenStudy (anonymous):

times by 100 100x-30x=2800 70x=2800 =40

OpenStudy (anonymous):

so the decimal by the 30 in the original problem doesn't matter when solving
