Ответ:

  1. \(4x=24+x\Rightarrow3x=24\Rightarrow x=8\).
  2. \(8x-8=20-6x\Rightarrow14x=28\Rightarrow x=2\).
  3. \(9-4x=3x-40\Rightarrow49=7x\Rightarrow x=7\).
  4. \(0.6x-5.4=-0.8x+5.8\Rightarrow1.4x=11.2\Rightarrow x=8\).
  5. \(4.7-1.1x=0.5x-3.3\Rightarrow8=1.6x\Rightarrow x=5\).
  6. \(\frac56x+16=\frac49x+9\Rightarrow\frac7{18}x=-7\Rightarrow x=-18\).

Ответ: 1) 8; 2) 2; 3) 7; 4) 8; 5) 5; 6) −18.
