In Exercises 39 to 42, use substitution to solve the system.
Use Example 9 as a guide.
The system described by the equations and using the method of substitution.
The general steps to be followed to solve a system of equations are described below.
Write each equation in the form of if it is not in the format.
Then equate the expressions for y.
Once the -coordinate of the solution is known, substitute this value of into either equation to find the value of y.
Here, one of the given equations is in the form and the value of is given.
So, substitute in .
It is given that .
So, the ordered pair is
Substitution of for in leads to,
