Solve the linear system, if possible, and use the result to determine whether the lines represented by the equations in the system have zero, one, or infinitely many points of intersection. If there is a single point of intersection, give its coordinates, and if there are infinitely many, find parametric equations for them. 3x - 2y = 4 6x - 4y = 9 Feb 01, 2007 · -Then if you know that y is -4x-7, its just a matter of putting -4x-7 where is y in the other equation, like this. 4x-2(-4x-7)=2. -Now you need to solve this new big equation, in order to find the value of x. Steps for Using the Substitution Method in order to Solve Systems of Equations. Solve 1 equation for 1 variable. (Put in y = or x = form) Substitute this expression into the other equation and solve for the missing variable. Substitute your answer into the first equation and solve. Check the solution.

There are many ways of writing linear equations, but they usually have constants (like "2" or "c") and must have simple variables (like "x" or "y"). 1. Explain why multiplication is sometimes needed to solve a system of equations by elimination. 2. OPEN ENDED Write a system of equations that could be solved by multiplying one equation by 5 and then adding the two equations together to eliminate one variable. 3. Describe two methods that could be used to solve the follOWing system of equations.
