Решите уравнения:

100+11x = - 8x+5

5 (2z-6) = 6z - 14

4+3t = 8t - t

4 (10-5y) - 4 = 0

100+11x = - 8x+5

11x+8x=5-100

19x=-95

x=-95:19

x = - 5

5 (2z-6) = 6z - 14

10z-30=6z-14

10z-6z=30-14

4z=16

z=16:4

z=4

4+3t = 8t - t

4+3t=7t

7t-3t=4

4t=4

t=1

4 (10-5y) - 4 = 0

40-20y-4=0

36-20y=0

20y=36

y=36:20

y=1,8
