1. rozwiaz rownania
a) 2 + x/2 = 1-x /3
b) - x+3 /5 - 1 =3 - 5x /2
c) 2(x+3) /9 - 4 = 2x+3 /6 -x
d) - 2x-1 /9 + 4x-5 /15 = x-5
e) - 5(x-2) /2 = 5- 3x /4
f) 1- [3(x+5) /2 + 3x /5] = -1
2. Rozwiaz rownania
a) 5:x=4:3 x ≠0
b) 3:5 = x:10
c) x /7 = 4/5
d) 5x-3 /9 = 3x+7 /5
e)3(x-1) /3 = -x-7 /5
f)x-3 /8 = x+3/12
g) 4+8x /2 = 3(x+13) /7
h) 5(x-2) /3 = 5x-2- /4
i) 4-x /3 = x+6 /2
j) 3(x-2) /5 = 4(x+3) /3
