-6(3n+1)+12n+9
5(0.6-1.5p)+8-3.5p
0.2(3a-1)+0.3-0.6a
0.9(2b-1)-0.5b+1
-2.6(5-c)-c+8
-3.6x-5.2-2.4x-9
4.6x+1.5b-3.2b-1.8a
-6.7a+5b-0.8a-2.5a
1.2x+3.4x-5-5.3x
2.4a-0.8m-0.4m-1.5a
-3.8y+2x+8y-4.3y
repedere va rog!!!!!!!!!!!!!!!!!!!!

Answer 1

3(2m+1)+4m-7=6m+3+4m-7=10m-4
-6(3n+1)+12n+9=-18n-6+12n+9=-6n-3
5(0.6-1.5p)+8-3.5p=3-7.5p+8-3.5p=-11p+11
0.2(3a-1)+0.3-0.6a=0.6a-0.2+0.3-0.6a=0.1    0.6a  cu 0.6a  se simplifica
0.9(2b-1)-0.5b+1=1.8b-0.9-0.5b+1=1.3b+0.1
-2.6(5-c)-c+8=-13+2.6c-c+8=-5-1.6c
-3.6x-5.2-2.4x-9=-6x-14.2
4.6x+1.5b-3.2b-1.8a=4.6x-1.7b-1.8a
-6.7a+5b-0.8a-2.5a=-10a+5b
1.2x+3.4x-5-5.3x=-0.7x-5
2.4a-0.8m-0.4m-1.5a=0.9a-1.2m
-3.8y+2x+8y-4.3y=-0.1y+2x

sper sa-ti fie de folos.....succese mari in continuare
