Question

1. 6 – 2у = 8 – 3у

2. 15х + 3 = 10х – 12

3. –5х – 11 = –6х – 12

4. 3х + 5 = 8х – 15

5. 5(х + 3) = 27 + 3х

6. 3у + (4 – 2у) = 6

7. 5у – (13 + у) = у + 14

8. 3(2х – 4) – 2(х + 3) = –2

9. 4у – 3 = 2(7 – у) + 1

Answer 1

Answer 2

1) 6-2у = 8-3у
6-8 = -3у +2у
-2 = -у
у=2

2) 15х+3=10х- 12
5х = -15
х=-3
3) -5х-11= -6х-12
х=-1

4) 3х+5 = 8х-15
20 = 5х
х=4

5) 5(х+3) = 27+3х
5х + 15 = 27 + 3х
2х = 12
х+6

6) 3у + 4 - 2у = 6
у = 2

7) 5у - 13 - у = у+14
3у = 27
у = 9

8) 3 ( 2х - 4) -2(х+3) = -2
6х - 12  - 2х - 6 + 2 = 0
4х = 16
х=4

9) 4у - 3 = 2(7-у) + 1
4у - 3 = 14 - 2у + 1
6у = 18
у=3
