Why do we solve systems of linear equations by graphing?To solve a system of linear equations by graphing, you will graph both lines and then see where they intersect each other. The x and y coordinates of the intersection will be the solution to the system of equations!
How do you solve system of linear equations?How do I solve systems of linear equations by substitution?. Isolate one of the two variables in one of the equations.. Substitute the expression that is equal to the isolated variable from Step 1 into the other equation. ... . Solve the linear equation for the remaining variable.. |
