Sigur
Explicație pas cu pas:
a) 2x+2= -5-x-4-7
2x+x=-2-5-4-7
3x=-18
x=-[tex]\frac{18}{3}[/tex]=-6
b) 5x+15+2x+2=-6x-24+8x-12+43
7x+17=2x-24-12+43
7x-2x=-24-12+43-17
5x=-10
x=-[tex]\frac{10}{5}[/tex]=-2
c) -6-(6-(-18-x)-9)=-11
-6-(6+18+x-9)=-11
-6-(15+x)=-11
-6-15-x+-11
-x=-11+21
-x=10
x=-10
d) 2x+10+(3-2x+6)=2-x-16+1
2x+10+(9-2x)=-13-x
19=-13-x
x=-13-19
x=-32
