3(x+1)=7(x-2)-3 --> 3x +3 =7x-14-3 -->20 = 4x-->x=5 I can't for the life of me figure out how the x=5 came about:( I'm too stressed, test at 10 a.m.

OpenStudy (experimentx):

x= 20/4

OpenStudy (anonymous):

right but I need to find out how you got the 20 and the 4, all I get are negatives

OpenStudy (experimentx):

could you add one step after second last step

OpenStudy (anonymous):

I can't now, I'm sorry, have to run
