rozwiąż równania 0,06x - 1+ 0,4x =0,27 - 0,04x 1/3 + 0,2=3/4x-0,6
0,06x-1 + 0,4x = 0,27 – 0,04x
0,06x + 0,4x + 0,04x = 0,27 +1
0,5x = 1,27 / : 0,5
x = 2,54
1/3 + 0,2 = ¾ x – 0,6
1/3 + 2/10 + 6/10 = 3/4x
3/4x = 1/3 + 8/10
¾x = 1/3 + 4/5
3/4x = 5/15 + 12/15
3/4x = 17/15
3x * 15 = 4 *17
45x = 68 /:45
x = 68/45
x = 1 23/45
