Answer 1

1. 3(х+4)-(3-4)-4-х = 3х+12-3-4 = 3х+5

2. х+4-5(2-х)-(5+1)х-5= -11

3. 4(х+4)-4(3-х)-х-5= 7х-1

4. х+2-4(5-х)-(4+1)х-2=-20

5. 2(х+4)-(1-х)-(1+2)х-2=5

6. х+2-(5-х)-х-1= -4+1

7. 4(х+2)-(1-х)-(1+4)х-5=8х+2

8. 4(х+2)-4(4-х)-х-2= 7х-10

9. 3(х+1)-4(5-х)-(4+3)х-2= -19

10. 3(х+3)-5(2-х)-х-4= 7х-5
