rozwiążcie mi to błagam przynajmniej niekture PLEASE...
1) 22x + 18 = 101+8x -13
2) 2(x-4)+3(2x+3)=4(x+2)-5(1-x)

4) 8+2(x+2)-3(x-1)=3x-1
5) 9y+1-18=4y-18+7y
6) x+17-3x=2x+11x+2
7) 5(x-3)=5x+7
8) 2x-8+3x=16-3x-8-x
9) 2x-1=3(x+4)-5(x-1)+6
10) 3(2x+42)-7(4x+2)=6(4x+8)-5(6x+4)
11) -2(3x+15)+4(-x+3)=2(3x-5)-3(2x+5)
12) 4x-21-3x-5x+2x-2=9
