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.
Solving systems of linear equations by elimination. Solving a system of linear equations by elimination means by adding or subtracting the equations to get rid of a common variable. Basic concepts: Adding and subtracting polynomials. Solving linear equations with variables on both sides. Determining number of solutions to linear equations.
