Matrices - solving two simultaneous equations
www.mathcentre.ac.ukWriting simultaneous equations in matrix form Consider the simultaneous equations x+2y = 4 3x−5y = 1 Provided you understand how matrices are multiplied together you will realise that these can be written in matrix form as 1 2 3 −5! x y! = 4 1! Writing A = 1 2 3 −5!, X = x y!, and B = 4 1! we have AX = B This is the matrix form of the ...

www.mathcentre.ac.uk2. Solving a pair of simultaneous equations There are many ways of solving simultaneous equations. Perhaps the simplest way is elimina-tion. This is a process which involves removing or eliminating one of the unknowns to leave a single equation which involves the other unknown. The method is best illustrated by example. Example Solve the ...

Solving simultaneous equations using matrix functions in …
educ.jmu.eduWhen solving simultaneous equations, we can use these functions to solve for the unknown values. For example, if you are faced with the following system of equations: a + 2b + 3c = 1 a –c = 0 2a + b = 1.25 Using matrix Algebra, [] [] [] To solve for the vector [], we bring the first matrix over to the right-hand side by dividing both sides by
