Question

Решите уравнения: 15x = 0,15 3,08 : y =4 3a +8a =1,87 7z - 3z = 5, 12

Answer 1

1) 15x=0.15

x=0.01

2) 3.08/y=4

y=3.08/4=0.77

3) 3a+8a =1.87

11a=1.87

a=0.17

4) 7z - 3z = 5.12

4z = 5.12

z=1.28

Answer 2

15x = 0,15

х=0,15:15

х=0,01

3,08 : y =4

у=3,08:4

у=0,77

3a +8a =1,87

11а=1,87

а=1,87:11

а=0,17

7z - 3z = 5,12

4z=5.12

z=5.12:4

z=1,28
