1)5x/3-4=3x/5
5x-12=9x/5
5×=9x+60/5
25x=9x+60
16x=60
x=60/16
x=15/4
2)2-9z/17-4z=4/5
10-45z=68-16z
16z-45z=68-10
-29z=58
z= -2
3)21-3(x-7)=x+20
21-3x-21=x+20
3x-x=20
2x=20
x=10
5)4x+1/3x-1=-2/1
4x+1=-6x+2
10x=1
x=1/10
4)3x/4-x-4/3=5/3
9x-4x-16/12=5/3
5x-16=20
5x=36
x=36/5
6)x2-(x+2)(x+3)/7x+1=2/3
x2-x2+3x+2x+6/7x+1=2/3
5x+6/7x+1=2/3
15x+18=14x+2
15x-14x=16
x=16
