Answer 1

А1. 3(х+3)-3(4-х)-х-3=3х+9-12+3х-х-3=5х-6
А2. 3(х+5)-(4-х)-(1+3)х-3=3х+15-4+х-х-3х-3=8
А3. 2(х+4)-3(2-х)-х-4=2х+8-6+3х-х-4=4х-2
А4. х+1-5(2-х)-(5+1)х-5=х+1-10+5х-5х-х-5=-14
А5. х+3-(2-х)-х-4=х+3-2+х-х-4=х-3
А6. 4(х+3)-(5-х)-х-4=4х+12-5+х-х-4=4х+3
А7. 3(х+3)-4(1-х)-(4+3)х-1=3х+9-4+4х-4х-3х-1=4
А8. 5(х+5)-3(3-х)-х-3=5х+25-3+3х-х-3=7х+19
А9. 2(х+2)-5(2-х)-(5+2)х-1=2х+4-10+5х-5х-2х-1=-7
А10. 2(х+4)-4(5-х)-(4+2)х-3=2х+8-20+4х-4х-2х-3=-15
