D
Step-by-step explanation:
The augmented matrix for the system of three equaitons is
Multiply the first row by 5, the second row by -3 and add these two rows:
Subtract the third row from the second:
Divide the third row by 6:
Now multiply the third equation by 26 and add it to the second row:
You get the system of three equations:
From the third equation
Substitute z=2 into the second equation:
Now substitute z=2 and y=5 into the first equation:
The solution is (1,5,2)
Answer:
