Uprość wyrażenie:
  • \( -(2x-1)-\Bigl(x-(5-3x)-1\Bigr) \)
  • \( -\Bigl((3y-2)-(4-5y)\Bigr)-(2y-(1-3y)) \)
  • \( -\Bigl(x-(2-(x-3))\Bigr)+(x-(4-(2x+1))) \)
  • \( -\Bigl(2a-(3-(a+4))\Bigr)-\Bigl(a-(5-(2a-3))\Bigr) \)
  • \( (5- (2-(x-1)))-\Bigl((3-(x-2))-(4-(x+3))\Bigr) \)
  • \( -\Bigl(4-(2-(y+3))\Bigr)+\Bigl((3y-2)-(1-(y-4))\Bigr) \)
  • \( -(2x-1)-\Bigl(x-(5-3x)-1\Bigr) \) \(= -2x+1 - \Bigl(x-5+3x-1\Bigr) \) \(= -2x+1 - (4x-6)\) \(= -2x+1-4x+6= -6x+7 \)
  • \( -\Bigl((3y-2)-(4-5y)\Bigr)-(2y-(1-3y)) \) \(= -\Bigl(3y-2-4+5y\Bigr)-\Bigl(2y-1+3y\Bigr) \) \(= -\Bigl(8y-6\Bigr)-\Bigl(5y-1\Bigr)\) \(= -8y+6-5y+1= -13y+7 \)
  • \( -\Bigl(x-(2-(x-3))\Bigr)+(x-(4-(2x+1))) \) \(= -\Bigl(x-(2-x+3)\Bigr)+(x-(4-2x-1)) \) \(= -\Bigl(x-(5-x)\Bigr)+(x-(3-2x)) \) \(= -\Bigl(2x-5\Bigr)+(3x-3)\) \(= -2x+5+3x-3= x+2 \)
  • \( -\Bigl(2a-(3-(a+4))\Bigr)-\Bigl(a-(5-(2a-3))\Bigr) \) \(= -\Bigl(2a-(3-a-4)\Bigr)-\Bigl(a-(5-2a+3)\Bigr) \) \(= -\Bigl(2a-(-a-1)\Bigr)-\Bigl(a-(8-2a)\Bigr) \) \(= -\Bigl(2a+a+1\Bigr)-\Bigl(a-8+2a\Bigr) \) \(= -(3a+1)- (3a-8)\) \(= -3a-1-3a+8= -6a+7 \)
  • \( (5-(2-(x-1)))-\Bigl((3-(x-2))-(4-(x+3))\Bigr) \) \(= \Bigl(5-2+x-1\Bigr)-\Bigl((3-x+2)-(4-x-3)\Bigr) \) \(= (x+2)-\Bigl((5-x)-(1-x)\Bigr) \) \(= (x+2)-\Bigl(5-x-1+x\Bigr)\) \(= (x+2)-4 = x-2 \)
  • \( -\Bigl(4-(2-(y+3))\Bigr)+\Bigl((3y-2)-(1-(y-4))\Bigr) \) \(= -\Bigl(4-2+y+3\Bigr)+\Bigl(3y-2-1+y-4\Bigr) \) \(= -\Bigl(y+5\Bigr)+\Bigl(4y-7\Bigr)\) \(= -y-5+4y-7= 3y-12 \)
