OpenStudy (anonymous):

Sure

jimthompson5910 (jim_thompson5910):

I'll give you a nudge 3x + 2 = 4x - 8 3x + 2 - 4x = -8 ... Subtract 4x from both sides. 3x - 4x = -8 - 2 ... Subtract 2 from both sides. Can you take over from here?

OpenStudy (anonymous):

yes let me try:)))))))

OpenStudy (anonymous):

jimthompson5910 (jim_thompson5910):

ok one sec

jimthompson5910 (jim_thompson5910):

OpenStudy (anonymous):

You combine like terms next

jimthompson5910 (jim_thompson5910):

still stuck?

OpenStudy (anonymous):

yes

jimthompson5910 (jim_thompson5910):

3x - 4x = -8 - 2 -1x = -10 .. Combine like terms. x = ??

OpenStudy (anonymous):

|dw:1367378496714:dw|

OpenStudy (anonymous):

3x+2=4x-8 =>3x-4x=-8-2 =>-x=-10 =>x=10
