Elimination with only the necessary row exchanges will produce the triangular factorization A = LPU , with the (unique) permutation P in the middle. The entries in L are reordered in comparison with the more familiar \\\(A={\\\widehat{P}\\\widehat{L}\\\widehat{U}}\\\) (where...
In algebra, some problems can be solved by using a process of elimination. Work through this process with increasingly complex sample problems by identifying the question, determining the known and unknown information, and applying elimination. ...

15. solve by the elimination method 0.05x+0.25y=66 0.15x+0.05y=72 16. the perimeter of a rectangle is 144 inches. The length exceeds the width by 52 inches. Find the length and the width 17. the everton college store paid $1972 for an order of 52 calculators. The store paid $9 ...
3x+y=9 3x+(2x+4)=9 5x+4=9 5x=5 x=1 This value of x can then be used to find y by substituting 1 with x e.g. in the first equation y=2x+4 y=2⋅1+4 y=6 The solution of the linear system is (1, 6). You can use the substitution ...
A third method ofsolving systems of linear equationsis theaddition method,this method is also called theelimination method. In this method, we add two terms with the same variable, but opposite coefficients, so that the sum is zero. Of course, not all systems are set up with the two terms...

In general, the solution of a system of (not necessarily linear) equations reduces to the solution of a single equation by means of the method of elimination of unknowns (see alsoRESULTANT). In analytic geometry we interpret an equation in two unknowns as a plane curve consisting of all po...
