*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ +\ y\ +\ z\ =\ 17000]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 0.1x\ +\ 0.12y\ +\ 0.15z\ =\ 2110]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ -\ y\ +\ z\ =\ 1000]


Solve the 3X3 system.  Recommend the substitution method to eliminate y first. Then solve for z in terms of x and solve the rest by substitution as well.
