a) 5x+3x-2x=5-2+4x
6x = 3+4x
2x=3 /:2
x=3/2=1,5
b) 8(x-2)-5=4-3(x+1)
8x-16=4-3x-3
11x-16=1
11x=17 /:11
x=17/11
c) 2=4x-3+5x-8-6x-3
-4x-5x+6x=-3-8-3+2
-3x=-12 /:-3
x=4
d)2(x-1)-3(3x=2)+4(x+5)=0
2x-1-9x-6+4x+20=0
-3x=1+6-20
-3x=-13 /:-3
x=13/3
e)5-3(4-2x)+3-2(5-x)=0
5-12+6x+3-10+2x=0
8x=-5+12-3+10
8x=24 /:8
x=3
f)8(x-4)+9-3(x+5)+38=0
8x-32+9-3x-15+38=0
5x=32-9+15-38
5x=0 /:5
x=0
