a)x=17/8

b)x=23

c)x=-28/11

Step-by-step explanation:

a) -3x+5=5x-12

-3x-5x=-12-5

-8x=-17

x=17/8

b) 6(x-3)-4(x+2)=20

6x-18-4x-8=20

6x-4x-18-8=20

2x-26=20

2x=20+26

2x=46

x=23

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

15[-2/5(x+3)]=15[1/3(x-2)]

-6(x+3)=5(x-2)

-6x-18=5x-10

-6x-5x=-10+18

-11x=28

x=-28/11
