- A1. 4(x + 2)-3(5-x) - x - 3= 4x
A1. 4(x + 2)-3(5-x) - x - 3= 4x + 8 - 15 + 3x - x - 3 = 6x - 10. A2. 3(x+3) 4(3- x) - (4 +3)x - 3= 3x + 9 - 12 + - 4x43x - 3 = 4x - 10. A3. 5(x + 4) - 5(-x) - x - 3 = 5x + 20+ 5x - x - 3 = 9x + 17. A4. 4(x + 1) - 5(5 - x) - (5 + 4)x - 1 = 4x + 4 - 25 + 5x9x - 1 -22. A5. 2(x + 2) - 5(4-x) - (5 + 2)x - 3= 2x + 4-20 + 5x - 7x3 = -19. A6. 4(x + 1) - 4(3 - x) - x - 5 = 4x + 4 -12 + 4x - x - 5 = 7x - 13. A7. 2(x + 4) - (2-x) - (1 + 2)x - 1 = 2x + 8-2 +x - x - 2x - 1 = 5. A8. x +4 -2(5-x) - x - 4 = x + 4 -10 + 2x - x - 4 = 2x - 10. A9. x + 5-(2-x) - (1+1)x - 1 = x + 5 - 2 + x - 2x - 1 = 2. A10.5(x + 1) - 2(5 - x) - x - 3= 5x + 5-10 + 2x - x - 3 = 6x - 8., Атвете ,меня если что Ваня завут.
