- \(11x+3=55-2x\), \(13x=52\), \(x=4\).
- \(4(x-6)=x-6\), \(4x-24=x-6\), \(3x=18\), \(x=6\).
- \(2-3(2+3x)=14\), \(-4-9x=14\), \(-9x=18\), \(x=-2\).
- \(-11x=7-3(5x-3)\), \(-11x=16-15x\), \(4x=16\), \(x=4\).
- \((8x+3)-(10x+7)=9\), \(-2x-4=9\), \(-2x=13\), \(x=-\frac{13}{2}\).
- \(8-3(x+1)=7-2x\), \(5-3x=7-2x\), \(-x=2\), \(x=-2\).
