Question Answer
x+5=15 x=10
2x+5=15 x=5
3x=15 x=5
3x+5=20 x=5
0,5x=4 x=8
0,5x+5=10 x=10
1/3 x = 13 x=39
1/3 x -4 = 5 x=27
0,1 x = 3 x = 30
1,1 x = 77 x = 70
0,7 x = 2,1 x =3
0,5 (x-4) = 4 x=12
-2 (x+3) = 12 x=-9
2- ( 2x-(6+2x))-x=0 x=8
x-(2-(2-(2-(2-x))))=0 równanie tożsamościowe czyli nieoznaczone, ma nieskończenie wiele rozwiazań
x-(x-(x-3))=0 x=3
