Determining Whether an Ordered Triple is a Solution: (1,3,2)(1, -3, 2)

To systematically evaluate whether the ordered triple (1,3,2)(1, -3, 2) functions as a solution to the system of linear equations given by \left\{\begin{array}{l} 3x + y + z = 2 \ x + 2y + z = -3 \ 3x + y + 2z = 4 \end{array} ight., substitute the precise values x=1x = 1, y=3y = -3, and z=2z = 2 uniformly into each of the original equations. The first linear equation evaluates as 3(1)+(3)+2=23(1) + (-3) + 2 = 2. The second equation calculates as 1+2(3)+2=31 + 2(-3) + 2 = -3. The final equation equates to 3(1)+(3)+2(2)=43(1) + (-3) + 2(2) = 4. Since all three distinct equations result cleanly in true arithmetic statements, the coordinate (1,3,2)(1, -3, 2) safely stands as a valid, comprehensive solution for the complete system.
