1). 15 - (x - 6) = 6 - (3x + 5) 2). (8x - 11) - (15 - x) = 1 3). 2(x - 5) - 5x = 8 - 3(5x - 2)

jimthompson5910 (jim_thompson5910):

I'll get you started 15 - (x - 6) = 6 - (3x + 5) 15 - x + 6 = 6 - 3x - 5 21 - x = 1 - 3x 21 = 1 - 3x + x 21 - 1 = -3x + x ... ... ... x = ???

OpenStudy (anonymous):

20 = -2x -10 = x x = -10

jimthompson5910 (jim_thompson5910):

good

jimthompson5910 (jim_thompson5910):

(8x - 11) - (15 - x) = 1 8x - 11 - 15 + x = 1 9x - 26 = 1 x = ???

OpenStudy (anonymous):

9x = 27 x = 3

jimthompson5910 (jim_thompson5910):

good again

jimthompson5910 (jim_thompson5910):

2(x - 5) - 5x = 8 - 3(5x - 2) 2x - 10 - 5x = 8 - 15x + 6 x = ???

OpenStudy (anonymous):

Okay, so x = 2.

jimthompson5910 (jim_thompson5910):
