Ответ:
Пошаговое объяснение:
1)
x+5-2(4-x)-x-4 = x + 5 - 8 + 2x - x - 4 = 2x - 7
2) 4(x+4)-5(2-x)-(5+4)x-3 = 4x + 16 - 10 + 5x - 9x - 3 = 3
3) 3(x+4)-3(5-x)-x-3 = 3x + 12 - 15 + 3x - x - 3 = 5x - 6
4) (x+3)-(2-x)-(1+4)x-2 = x + 3 - 2 + x - 5x - 2 = -3x - 1
5) 3(x+5)-4(5-x)-(4+3)x-1 = 3x + 15 - 20 + 4x - 7x - 1 = -6
6) 3(x+2)-4(1-x)-x-4 = 3x + 6 - 4 + 4x - x - 4 = 6x - 2
7) 4(x+2)-4(2-x)-(4+4)x-3 = 4x + 8 - 8 + 4x - 8x - 3 = -3
