Use substitution to solve the following system of equations. X + 4y = 1. 2x – 3y = -9. Step1 –Choose a variable to solve for in either equation. I will choose x from the first equation because it has a coefficient of 1 (there is no number next to it) and it will be easy to solve for x. X= 1- 4y. Step 2 - …

Solving Systems of Equations. In order to solve for two variables, you need to have two equations. If you only have one equation there are an infinite amount of ordered pairs (x,y) that will work. For example: 4x – 2y = 16 you can have x = 4 and y = 0 (4,0) and (2, -2) and (0, -4) and an infinite amount of others.

For example, both x = 1,y = 2,z = 3 and x = -2,y = -3,z = -1 are valid for the system of two equations. Both of these problems illustrate that sometimes it is possible to manipulate a set of given equations to solve for a quantity without having to solve for each individual variable in that quantity.
