Question

решите пожалуйста....

Answer 1

1) -10y - 64 = -6y

-10y + 6y = 64

-4y = 64

-y = 16

y = -16

2) 9m - 8 = 6m + 7

9m - 6m = 7 + 8

3m = 15

m = 5

3)6x + 10 = 5x + 15

6x - 5x = 15 - 10

x = 5

4)16m - 5 = 15m - 10

16m - 15m = -10 + 5

m = -5

5)8 - 5n = 10 - 4n

-5n + 4n = 10 - 8

-n = 2

n = -2

6)18 = 3y + 3

-3y = 3 - 18

-3y = -15

y = 5
