2x+7/5-3x+11/2 = 2x+8/3 -5
2x-2x-3x=8/3-5-7/5-11/2
-3x*30=8/3-5-7/5+11/2 The comm denomunator is 30
-90x=8*10-5*30-7*6-11*15
-90x=80-150-42-165
-90x=-277 / * -1
90x=277
x=277/90
2x-2x-3x=8/3-5-7/5-11/2
-3x*30=8/3-5-7/5+11/2 The comm denomunator is 30
-90x=8*10-5*30-7*6-11*15
-90x=80-150-42-165
-90x=-277 / * -1
90x=277
x=277/90
