Ответ:
- \(-5x+6=2x-9\Rightarrow15=7x\Rightarrow x=\frac{15}{7}\).
- \(-5x-3=-x+10\Rightarrow-4x=13\Rightarrow x=-\frac{13}{4}\).
- \(-0.5x-5.1=x+4.9\Rightarrow-10=1.5x\Rightarrow x=-\frac{20}{3}\).
- \(3.5x-2.5=-x-3.6\Rightarrow4.5x=-1.1\Rightarrow x=-\frac{11}{45}\).
- \(x=3.6-3x\Rightarrow4x=3.6\Rightarrow x=0.9\).
