a) 2x+3/5 = 2-x/3-x /*15
3(2x+3)=5(2-x)-15x
6x+9=10-5x-15x
6x+9=10-20x / +20x, -9
26x=1/:26
1/26
x+1/2 - x-1/3 = 1/4
6(x+1)-4(x-1)=12/4
6x+6-4x+4=3
2x+10=3/-10
2x=-7/:2
x=-7/2
x=-3 i 1/2
4x+7/2 - 5x-1/6= x+5/*6
3(4x+7)-(5x-1)=6(x+5)
12x+21-5x+1=6x+30
7x+22=6x+30/-6x,-22
x=8
x+5/4 - 2x+1/8 = 1/2(2-x) / *8
2(x+5)-(2x+1)=4(2-x)
2x+10-2x-1=8-4x
9=8-4x /-8
1=-4x/:(-4)
- 1/4 = x
mam nadzieje ze pomoglem
