There are three types of systems of linear equations in two variables, and three types of solutions.An independent system has exactly one solution pair (x,y) . The point where the two lines intersect is the only solution.An inconsistent system has no solution.A dependent system has infinitely many solutions.

Add 4 to both sides. Plug 1 9 19 19 for y into the first equation. The unique solution is ( 2 1 , 1 9 ) (21,19) (21,19). There are three ways to solve systems of linear equations: substitution, elimination, and graphing.

There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form. We review all three in this article.

In order to solve systems of equations in three variables, known as three-by-three systems, the primary goal is to eliminate one variable at a time to achieve back-substitution. A solution to a system of three equations in three variables (x,y,z), ( x , y , z ) , is called an ordered triple.

A system of two equations can be classified as follows: If the slopes are the same but the y-intercepts are different, the system is inconsistent. If the slopes are different, the system is consistent and independent. If the slopes are the same and the y-intercepts are the same, the system is consistent and dependent.
