Решите плиз уравнения
1. –5(3х + 1) – 11 = –1
2. –8у + 4 = –2(5у + 6)
3. 20 + 30х = 20 + х
4. 26 – 5у = 2 – 9у
5. 9х + 11 = 13х – 1
6. 12х + 31 = 23х – 2
7. 2(х – 2) – 1 = 5(х – 2) – 7
8. 4(2х – 6) = 4х – 4
9. –9у + 3 = 3(8у + 45)
10. 20 + 5х = 44 + х
1. –5(3х + 1) – 11 = –1
2. –8у + 4 = –2(5у + 6)
3. 20 + 30х = 20 + х
4. 26 – 5у = 2 – 9у
5. 9х + 11 = 13х – 1
6. 12х + 31 = 23х – 2
7. 2(х – 2) – 1 = 5(х – 2) – 7
8. 4(2х – 6) = 4х – 4
9. –9у + 3 = 3(8у + 45)
10. 20 + 5х = 44 + х
