Systems of Linear Equations: Applications and …
WebMar 26, 2016 · But when equations get more complicated, a better way to solve system is by combining equations. For example: 12x – 9y = 37 8x + 9y = 23. Neither equation in this system makes clear the value of one variable in terms of another, making substitution difficult. To solve this system more easily, add the two equations as follows: WebThe next few slides provide some examples of how to apply the systems of equations to some common word problem situations.
