Question

What is the solution to the system of equations?
-3 x - 4y - 3z= -7
, 2x - 6 y + 2z= 3,
5 x - 2y + 5 Z=9
Answers:
A, (5, -2, 7)
B, (-5, 2, 7,)
C, (5,2,-7)
D, No solution

Answer 1

Solution

Step 1: Isolate the variable x and plug in the values of x in the second and third equations.

Step 2: Isolate variable y and solve for y.

We get the value of y = 5/26

When we substitute the value of y , 1 = 0 which is not true.

Therefore, this system has No Solution.

Answer: No solution
