Question

Решить уровнение............. ​

Answer 1

4х+30=6х

30=6х-4х

30=2х

х=15

4+25у=6+24у

25у-24у=6-4

у=2

3у+7=-4у-7

3у+4у=-7-7

7у=-14

у=-2

Answer 2

Ответ:

1)

4x + 30 = 6x

4x - 6x = -30

-2x = -30

x = -30 : (-2)

x = 15

2)

4 + 25y = 6 + 24y

25y - 24y = 6 - 4

y = 2

3)

3y + 7 = -4y - 7

3y + 4y = -7 - 7

7y = -14

y = -14 : 7

y = -2
