d) 2x - 1-3x/10 - 2/3 = 2 (x-3) + 1/5
ayuda porfa con los procesos

Answer 1

x/2 +3/5 = 4/3 - x/6

x/2+x/6 = 4/3-3/5

2x/3 = 11/15

2x = 33/15

x = 33/30 = 11/10

====================

2x-1/5-5 = x+4/3-7/2

2x-x = 4/3-7/2+1/5+5

x = -13/6+26/5

x = 91/30

===============

 x/3 + x/5 + 1 =3x/4 - 1

x/3+x/5-3x/4 = -1-1

8x/15-3x/4 = -2

-13x/60 = -2

-13x = -120

x = 120/13

==================
2x - 1-3x/10 - 2/3 = 2 (x-3) + 1/5

2x - 1-3x/10 - 2/3 = 2x-6 + 1/5

2x-3x/10-2x = -6+1/5+1+2/3

-3x/10 = -5 + 1/5+2/3

-3x/10 = -5+13/15

-3x/10 = -62/15

-3x = -620/15

x = 620/45 = 124/9
