**How do you solve x+2y=9 and x+y=1 using matrices? Socratic**

Hi guys, today we are going to teach you how to model a bus admittance matrix (Y-bus) of a given power system. Modeling and solving of Y-bus matrices is an important part of Power system analysis and design, and is used extensively in diagnosing, solving and finding problems in power systems especially different kind of faults.... 2011-05-03 · Best Answer: First, let me suggest that you be very careful with the dimensions of matrices. 2x3 is NOT the same as 3x2. The example you gave was a 2x3, and I will assume that's what your chemistry problem gave. The easiest way to solve a system of n equations in n unknowns is to use a graphing calculator

Now I can divide through to solve for x = 5, and then back-solve, using either of the original equations, to find the value of y. The first equation has smaller numbers, so I'll back-solve in that one:... The given equations can be written as a matrix: #color(white)("XXXX")xcolor(white)("X")ycolor(white)("X")=c# #color(white)("XXX")((color(red)(1),color(blue)(2),,color
