Answer to Problem 12WE

  {x,y,z}={3,−3,4}

Explanation of Solution

Given:

  2x−y=3z−33x+2y=z−1x+3y=z−10

Calculation:

Given equation are as follows:

  2x−y=3z−3.....................(1)3x+2y=z−1.....................(2)x+3y=z−10......................(3)

Solve for z in equation 2:

  3x+2y=z−13x+2y+1=zz=3x+2y+1.....................(4)

Put the value z from equation (4) in equation (3):

  x+3y=z−10x+3y=3x+2y+1−100=3x+2y−9−x−3y0=2x−y−99=2x−y2x−y=9.....................(5)

Put the value z from equation (4) in equation (1):

  2x−y=3z−32x−y=3(3x+2y+1)−32x−y=9x+6y+3−30=9x+6y−2x+y7x+7y=07(x+y)=0x+y=0x=−y.....................(6)

Put the value of x from equation (6) in equation (5) and calculate y:

  2x−y=92(−y)−y=9−2y−y=9−3y=9y=−93y=−3.....................(7)

Put the value of y from equation (7) in equation (6) and calculate x:

  x=−yx=−(−3)x=3.....................(8)

Put the value of y and x from equation (7) and (8) in equation (4) and calculate z:

  z=3x+2y+1z=3(3)+2(−3)+1z=9−6+1z=3+1z=4.....................(9)

Hence, from equation (7),(8),(9): {x,y,z}={3,−3,4}

Conclusion:

  {x,y,z}={3,−3,4}
