To solve: the system by the method of elimination.
Answer to Problem 6CT
The solution of above system of equations is (1, 0, −2).
Explanation of Solution
Given information :
System of equations are given as,
Multiplying 1 by ‘2’ and solving (1) and (2),
Now, multiplying 2 by ‘3’ and 3 by ‘2’,
Solving (4) and (5),
Multiplying (4) by 3 and solving,
Further,
Putting z = −2 in (5),
Further,
Putting y = 0 and z = −2 in (1),
So, the solution of above system of equations is (1, 0, −2).
