I have 3 equations and 3 unknowns. Is there a way to solve for them?
4*x + 5*y + 6*z = 7
3*x + 2*y + 4*z = 5
2*x + 7*y + 5*z = 9

- subs() 0 for x, y, and z all, to find the constants.
- subs() 1 for x, 0 for y and z, and subtract the constants from #1, to find the coefficients for x.
- likewise (0,1,0) and (0,0,1) to find y and z coefficients.
