SOLUTION: 1/2x - 1/3y - 1/2z = 1/10 1/3x - 1/4y + 1/3z = 1/8 1/4x - 1/5y + 1/4z = 1/10

Algebra ->  Coordinate Systems and Linear Equations -> SOLUTION: 1/2x - 1/3y - 1/2z = 1/10 1/3x - 1/4y + 1/3z = 1/8 1/4x - 1/5y + 1/4z = 1/10      Log On


   

Question 1020456: 1/2x - 1/3y - 1/2z = 1/10
1/3x - 1/4y + 1/3z = 1/8
1/4x - 1/5y + 1/4z = 1/10
