Hi guys! This video discusses how to solve systems of linear equations by substitution method.We do the substitution method by solving one variable say y explicitly in terms of the other variable, x usinh any of the two equations. Then substitute that value of y to the second equation and solve for the other variable which is x. Then we can solve the other variable y by substituting the obtained value of the first variable on any of the given two equations. We still apply the different types of systems of linear equations such as consistent, inconsistent and dependent for the expected solutions or graphs of the systems. We illustrate several examples on solving systems of linear equations by substitution method. Happy learning and enjoy watching! #math #tagalog #solvingsystemsoflinearequationsbysubstitutionmethod
