Question

1) 5x - 16 = 14;
2) 8y = 10 + 3y;
3) 24x - 16 = 8 + 12x;
4) 12-y= 2y +6;
15) 3.x + 3 = 27 -5.X;
(6) 3y - 8=2y+7.​

Answer 1

Ответ:

5х-16=14

5х=16+14

5х=30

х=30:5

х=6

8у=10+3у

5у=10

у=10:5=2

24х-16=8+12х

24х-12х=16+8

12х=24

х=24:12

х=2

12-у=2у+6

-у+2у=6-12

у= -6

3х+3=27-5х

3х+5х=27-3

8х=24

х=24:8

х=3

3у-8=2у+7

3у-2у=7+8

у=15

Answer 2

1)5х-16=14

5х=14+16

5х=30

х=30:5

х=6

2)8у=10+3у

8у-3у=10

5у=10

y=2

3)24x - 16 = 8 + 12x

24х-12х=8+16

12х=24

х=2

4) 12-y= 2y +6

-y-2y=6-12

-3y=-6

y=2

15)3x + 3 = 27-5x

3х+5х=27-3  

8х=24

х=24/8

х=3

6)3y - 8=2y+7

3y-2y=7+8

y=15
