Q. Solve the system.\newline{x+3yz=6 2xy+z=10 xy+3z=2\begin{cases} x+3y-z&=-6 \ -2x-y+z&=10 \ x-y+3z&=2 \end{cases}
  1. Write Equations: Write down the system of equations.\newlineThe system of equations is:\newlinex+3yz=6x + 3y - z = -6\newline2xy+z=10-2x - y + z = 10\newlinexy+3z=2x - y + 3z = 2
  2. Elimination Method: Use the elimination method to eliminate one variable.\newlineWe can start by eliminating the variable zz. To do this, we can add the first and second equations to eliminate zz.\newline(x+3yz)+(2xy+z)=6+10(x + 3y - z) + (-2x - y + z) = -6 + 10\newlineThis simplifies to:\newlinex+2y=4-x + 2y = 4
  3. Solve for xx and yy: Now we have a new system of two equations with two variables.\newlineThe new system is:\newlinex+2y=4-x + 2y = 4\newlinexy+3z=2x - y + 3z = 2
  4. Equations with y and z: Solve the new system for x and y.\newlineWe can solve for x from the first equation of the new system:\newlinex+2y=4-x + 2y = 4\newlinex=2y4x = 2y - 4\newlineNow we substitute x in the second equation:\newline(2y4)y+3z=2(2y - 4) - y + 3z = 2\newliney4+3z=2y - 4 + 3z = 2\newliney+3z=6y + 3z = 6
  5. Solve for y and z: We now have two equations with y and z.\newlineThe equations are:\newliney+3z=6y + 3z = 6\newline2xy+z=10-2x - y + z = 10\newlineWe can substitute x from step 44 into the second equation:\newline2(2y4)y+z=10-2(2y - 4) - y + z = 10\newline4y+8y+z=10-4y + 8 - y + z = 10\newline5y+z=2-5y + z = 2
  6. Find zz: Solve the system of equations with yy and zz. We have two equations: y+3z=6y + 3z = 6 5y+z=2-5y + z = 2 We can multiply the first equation by 55 to eliminate yy: 5(y+3z)=5(6)5(y + 3z) = 5(6) 5y+15z=305y + 15z = 30 Now we add this to the second equation: 5y+15z+(5y+z)=30+25y + 15z + (-5y + z) = 30 + 2 This simplifies to: 16z=3216z = 32 z=3216z = \frac{32}{16} z=2z = 2
  7. Find yy: Substitute zz back into one of the equations to find yy. We can use the equation y+3z=6y + 3z = 6: y+3(2)=6y + 3(2) = 6 y+6=6y + 6 = 6 y=66y = 6 - 6 y=0y = 0
  8. Find xx: Substitute yy back into the equation from step 44 to find xx. We use the equation x=2y4x = 2y - 4: x=2(0)4x = 2(0) - 4 x=4x = -4
  9. Final Solution: Write down the solution to the system of equations.\newlineThe solution is x=4x = -4, y=0y = 0, z=2z = 2.
