Solve for x, y, z, a, b, t
x = -\frac{240}{223} = -1\frac{17}{223} \approx -1.076233184
y=-\frac{90}{223}\approx -0.403587444
z=\frac{215}{223}\approx 0.964125561
t = -\frac{900}{223} = -4\frac{8}{223} \approx -4.035874439
a=-\frac{150}{223}\approx -0.67264574
b = \frac{3300}{223} = 14\frac{178}{223} \approx 14.798206278
