@hoblos

OpenStudy (anonymous):

combine like terms

OpenStudy (hang254):

so combine 0.2x- 8x

OpenStudy (anonymous):

so its -7.8x-11.4=0.9

OpenStudy (anonymous):

yes, then you would add 11.4 to both sides

OpenStudy (anonymous):

which is 12.3 then divide 2.3 by -7.8

OpenStudy (anonymous):

which is how i got -1.5769 but you can round it to -1.58

OpenStudy (hang254):

oh, thank you so much! this will help me in my class :)

OpenStudy (anonymous):

welcome! :))

OpenStudy (hang254):

one more thing. if it was 0.2x + .6 - 8x + 12= 0.9 would the answer be positive 1.5?

OpenStudy (anonymous):

no, it would be -1.6

OpenStudy (anonymous):

I got x=1.5 even

OpenStudy (anonymous):

hmm.....i check my work

OpenStudy (anonymous):

OpenStudy (anonymous):
