Ответ:
- \(3x+5+(x+5)=(1-x)+4\)
\(4x+10=5-x\)
\(5x=-5\)
\(x=-1\). - \(x-3-4(x+1)=5(4-x)-1\)
\(-3x-7=19-5x\)
\(2x=26\)
\(x=13\). - \(4x+4-3(x+1)=5(-x-1)+5\)
\(x+1=-5x\)
\(6x=-1\)
\(x=-\frac{1}{6}\). - \(2x+2a+3(x+4)=-4(1-x)+3\)
\(5x+2a+12=4x-1\)
\(x=-2a-13\). - \(-3x+1+(x-5)=5(3-x)+5\)
\(-2x-4=20-5x\)
\(3x=24\)
\(x=8\). - \(-x-4+5(x+3)=5(-1-x)-2\)
\(4x+11=-5x-7\)
\(9x=-18\)
\(x=-2\). - \(-3x+1-3(x+3)=-2(1-x)+2\)
\(-6x-8=2x\)
\(-8x=8\)
\(x=-1\). - \(-5x-2+4(x+1)=4(-3-x)-1\)
\(-x+2=-4x-13\)
\(3x=-15\)
\(x=-5\).
