In Example 3, change the constant to the right of the = sign in the first equation
Question:
In Example 3, change the constant to the right of the = sign in the first equation from −1 to −3, change the constant to the right of the = sign in the third equation from 9 to 11, and then solve the resulting system of equations.
Data from Example 3
Solve the following system by determinants.
Substituting in each of the original equations shows that the solution checks:
After the values of x and y were determined, we could have evaluated z by substituting the values of x and y into one of the original equations.
