Simplify —— x3. 1.1 x2 divided by x3 = x(2 - 3) = x(-1) = 1/x1 = 1/x. How did we do? Please leave us feedback.

Let x_3 = 0 then, x_1-x_2 = 5-x_4, x_1+x_2 = x_4+2. So, x_1 = 3.5, x_2 = x_4-1.5 and x_1+x_2+x_3+x_4 = 2x_4+2 is unbounded. Your system is underdetermined, because equations x_1+x_3=1 and x_2+x_4=1 are already implied by the first four equations. That's why Mathematica gives the solution as a function of y. You need ...
