Пошаговое объяснение:
1. 3(х+3)-3(4-х)-х-3 = 3x + 9 - 12 + 3x - x - 3 = 5x - 6
2. 3(х+5)-(4-х)-(1+3)х-3 = 3x + 15 - 4 + x - 4x - 3 = 8
3. 2(х+4)-3(2-х)-х-4 = 2x + 8 - 6 + 3x - x - 4 = 4x - 2
4. х+1-5(2-х)-(5+1)х-5 = x + 1 - 10 + 5x - 6x - 5 = -14
5. х+3-(2-х)-х-4 = x + 3 - 2 + x - x - 4 = x - 3
6. 4(х+3)-(5-х)-х-4 = 4x + 12 - 5 + x - x - 4 = 4x + 3
7. 3(х+3)-4(1-х)-(4+3)х-1 = 3x + 9 - 4 + 4x - 7x - 1 = 4
8. 5(х+5)-3(3-х)-х-3 = 5x + 25 - 9 + 3x - x - 3 = 7x + 13
9. 2(х+2) – 5(2-х)-(5+2)х-1 = 2x + 4 - 10 + 5x - 7x - 1 = -7
10. 2(х+4)-4(5-х)-(4+2)х-3 = 2x + 8 - 20 + 4x - 6x - 3 = -15
