The hip fusion is better tolerated by male than by female patients. The results depend on the position in which the hip has been fused. Too much of a bent position in the thigh and the adducted thigh (thigh drawn to the midline) can result in pain in the spine.
The three types of solution sets: A system of linear equations can have no solution, a unique solution or infinitely many solutions. A system has no solution if the equations are inconsistent, they are contradictory. for example 2x+3y=10, 2x+3y=12 has no solution. is the rref form of the matrix for this system.
A system of equations is set of equations that deal with all together at once. It is simpler than non linear equations. The simplest system of linear equations is the one which has two equations and two variables.
