WebIn this explainer, we will learn how to solve a system of three linear equations using the inverse of the matrix of coefficients. We can solve a system of linear equations, which are also called simultaneous equations, using the substitution or elimination methods, but these methods become convoluted when the number of equations are more than two. Web1 Write the simultaneous equations as a matrix equation in the form AX = B. Matrix A is the matrix of the coefficients of x and y in the simultaneous equations, X is the matrix of the …
