The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently. In this example, the ordered pair (4, 7) (4,7) is the solution to the system of linear equations. We can verify the solution by substituting the values into each equation to see if the ordered pair satisfies both equations.

Solution. We can obtain an equation in one variable by adding Equations (1) and (2) Solving the resulting equation for x yields. 2x = 6, x = 3. We can now substitute 3 for x in either Equation (1) or Equation (2) to obtain the corresponding value of y. In this case, we have selected Equation (1) and obtain. (3) + y = 5.
