A system of linear equation can be solved in two ways. One way is solving by which uses the coordinates of the point of as the answers. Another way is called . In this method we creates opposites to eliminate one of the variables and solve for the other variable. The last method is solving by . In this method we isolate a variable and substitute what is equal to that in the other equation for that variable and solve the last equation that we get.

Answer 1

Graphing, elimination, substitution are the three methods in order of the question

Explanation:

Answer 2

Answer:\Another way to solve a system of equations is by substitution. With this method, you are essentially simplifying one equation and incorporating it into the other, which allows you to eliminate one of the unknown variables. Consider the following system of linear equations:
