Final answer:
To solve the given system of equations, use the method of substitution.
Step-by-step explanation:
To solve the given system of equations, we can use the method of substitution.
Step 1: Rewrite the first equation as 2x + y = 9 - 32.
Step 2: Simplify the equation to get 2x + y = -23.
Step 3: Substitute the value of y from the second equation into the first equation to get 2x + 2Py = -23.
Step 4: Solve for x using the equation.
Step 5: Substitute the value of x into the second equation to solve for y.
Step 6: Substitute the values of x and y into the third equation to solve for z.
The values of x, y, and z are x = 6.5, y = -2, and z = -1.67.
