0.2t+1,7t-0,54=0,22
5.6z-2z-0.7z+2.65=7

Answer 1

0,2t+1,7t-0,54=0,22
1,9t=0,22+0,54
1,9t=0,76
t=0,76:1,9
t=0,4




================
5,6z-2z-0,7z+2,65=7
2,9z=7-2,65
2,9z=4,35
z=4,35:2,9
z=1,5

Answer 2

0.2t+1,7t-0,54=0,22 
1.9t=0.22+0.54
1.9t=0.76
t=0.76:1.9
t=0.4

5.6z-2z-0.7z+2.65=7
2.9z=7-2.65
2.9z=4.35
z=4.35:2.9
z=1.5
