Ayudenme Por Favor!!! ​

Answer 1

Explicación paso a paso:

7y = 28

y = 28 / 7

y = 4

w / - 5 = 3

w = 3 x - 5

w = - 15

4x = 2 / 7

x = ( 2 / 7 ) / 4

= 2 / ( 7 x 4 )

= 1 / ( 7 x 2 )

x = 1 / 4

4m = 10 - 20

4m = - 10

m = - 10 / 4

m = - 2 / 5

7y + 5 = 10y - 4

5 + 4 = 10y - 7y

9 = 3y

y = 9 / 3

y = 3

10x + 5 = 5x + 6

10x - 5x = 6 - 5

5x = 1

x = 1 / 5
