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!

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. Solving equations with addition Solving equations with multiplication/division Solving one-step equations: combined Solving two-step equations Solving Equations involving Like Terms Solving Equations using Distribution Solving equations with variables on both sides Clearing Equations of Fractions Clearing Equations of Decimals
