Verified answer

Пошаговое объяснение:

1) 3(х+3)-3(4-х)-х-3= 3х+9-12+3х-х-3=5х-6

2) 3(х+5)-(4-х)-(1+3)х-3= 3х+15-4+х-4х-3= 8

3) 2(х+4)-3(2-х)-х-4= 2х+8-6+3х-х-4= 4х-2= 2(2х-1)

4) х+1-5(2-х)-х(5+1)-1= х+1-10+5х-6х-1= -10

5) х+3-(2-х)-х-4= 3-2+х-4= х-3

6) 4(х+3)-(5-х)-х-4= 4х+12-5+х-х-4= 4х+3

7) 3(х+3)-4(1-х)-(4+3)х-1= 3х+9-4+4х-7х-1= 4

8) 5(х+5)-3(3-х)-х-3= 5х+25-9+3х-х-3= 7х+13

9) 2(х+2)-5(2-х)-(5+2)х-1= 2х+4-10+5х-7х-1= -7

10) 2(х+4)-4(5-х)-(4+2)х-3= 2х+8-20+4х-6х-3= -15
