Пошаговое объяснение:
(8x+3)-(10x-6)-9= 8х+3-10х+6-9=-2х
1. 3( x+6)-x-2(x+9)=3x+18-x-2x-18=0
2. 6-3(x+1)-(7-x)=6-3x-3-7+x=-4-2x
3.(8x+3)-(10x-6)-9=8x+3-10x+6-9=-2x
4. 5-2(x-1)-(-4-x)=5-2x+2+4+x=11-x
5. (7x+1)-(9x+3)+5=7x+1-9x-3+5=-2x+3
6. (3.4+2y)-7(y-2,3)=3,4+2y-7y+16,1=19,5-5y
7. 4(5x+2)-10(3x-3)+15=20x+8-30x+30+15=-10x+53
8. 4(x-1)-2(2x-8)+12=4x-4-4x+16+12=24
9. 5,6-3(2-0,4x)-0,4(4x-1)=5,6-6+1,2x-1,6x-0,4=-0,4x
10. 5(x-12)+6(x-10)-(x-1)=5x-60+6x-60-x+1=10x-119
