Помогите 1. 6x + 10 = 4x + 12. (x; 3) 2. 7x + 25 = 10x + 16. (x; 6) 3. 3y + 16 - 8y - 9. (5; y) 4. 0,4(6y - 7) = 0,5(3y + 7). (5; y) 5. 4(3 - x) = 7(2x - 5). (x; 8) 6. 9,6 - (2,6 + x) = 4. (x; 8) 7. 1,7 - 0,6a = 0,3 - 0,4a. (~ 6; a) 8. 17 - 4x = 5 - 6x. (x; 5) 9, 2,8 - 3,2x = - 4,8 - 5,1x. (x; 6) 10. 0,2(5x - 2) = 0,3(2x - 1) - 0,9. (x; 3) 11. 5m + 27 = 4m + 21. (m; - 4) 12. 4(1 - 0,5a) = - 2(3 + 2a). (a; - 7) 13. 3y - 17 = 8y + 18. (4: y) 14. 1 - 5(1,5 + x) = 6 - 7,5x. (x; - 4) 15. 2y - 1,5(y - 1) = 3. (1; y)
