When you solve a linear system you find that one point makes both equations true. What point is the solution to the system above? _____ Plot both equations in the same coordinate plane below. y = -2x and y = x + 3. At what point do the two lines intersect? _____ Compare this with your answer for #4…

There are two ways to solve a system of equations (algebraically and graphically). We will focus on solving algebraically. There are two methods of solving algebraically (substitution and elimination). The key to both of them is changing one (or both) equations so there is only one variable to solve for.

Solve the system. Select the first and second equations to eliminate the z variable (multiply the second equation by 2 and add). Select the second and third equations to eliminate the same z variable (multiply the second equation by (3 and add). You now have two equations in terms of x and y.

You can use algebra to solve two equations in two variables by reducing the equations to one equation in one variable. One way to do this is to use the . substitution method. Consider the system 2. x + y = 7 and . x ... Then use the substitution method to solve the system. Show your work to the right.

Use substitution to solve the system of equations. If the system does not have one solution tell whether it has infinitely many solutions or no solution. Y = 2x + 1. 2y = 4x +2. Step 1 - Choose a variable to solve for. Look for the easiest way to solve the problem. Because the first equation is already solved for y I will choose the first equation.
