To substitute, first solve one of the equations in terms of . x. or . y. Solving for . x, the second equation becomes: x = – y + 2. Substituting (–y + 2) for . x. into the first equation: 2(–y + 2) – 3. y = 10 Doing this gives us an equation without . x. Solving for . y Solve systems of linear equations, given in slope-intercept form, both graphically and algebraically. Use a draggable green point to examine what it means for an ( x, y) point to be a solution of one equation, or of a system of two equations. Time's Up!

- Fill the system of linear equations: To change the signs from "+" to "-" in equation, enter negative numbers. If in your equation a some variable is absent, then in this place in the calculator, enter zero. You can input only integer numbers or fractions in this online calculator.
- Solving a linear system in two variables by graphing works well when the solution consists of integer values, but if our solution contains decimals or fractions, it is not the most precise method. We will consider two more methods of solving a system of linear equations that are more precise than graphing.

- In elementary algebra, the quadratic formula is a formula that provides the solution(s) to a quadratic equation. There are other ways of solving a quadratic equation instead of using the quadratic formula, such as factoring (direct factoring, grouping, AC method), completing the square, graphing and others.

Graphing systems of equations involves graphing each individual linear equation in the system. The places where the lines intersect represent solutions where two or more of the linear equations share a common solution, and that point is regarded as the solution to the entire system. You can solve a system of equations by graphing the lines and ... There are two methods that will be used in this lesson to solve a system of linear equations algebraically. They are 1) substitution, and 2) elimination. They are both aimed at eliminating one variable so that normal algebraic means can be used to solve for the other variable.
