Student Exploration: Solving Linear Systems . Activity A: Using substitution Get the Gizmo ready: On the CONTROLS. tab, turn off . Check solution at point. 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.
Solving Systems of Linear Equations
If a point works in both equations of a linear system, then that point must be the SOLUTION to the linear system. 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
