Помогите пожалуйста!!!!!!

Answer 1

1. = 4х+12-6=2х-х-4=5х+2                           9. = 4х+4-16+4х-8х-3=0-15=-15
2. = 5х+10-12+3х-8х-2=0-4=-4                   10. = 5х+25-15+5х-х-1=9х+9
3. = 3х+15-20+6х-х-3=7х-8
4. = 5х+15-2+2х-7х-2=0+11=11
5. = 3х+12-1+х-4х-3=0+8=8
6. = 5х+10-10+5х-х-1=9х-1
7. = 2х+2-6+2х-4х-5=0-9=-9
8. = -3+х
