Question

Solve the following system of equations.

4x + 7y – 2z = 0
3x – 5y + 3z = 9
3x + 6y – z = 1

(–1, 0, –2)

(1, 0, –2)

(–1, 0, 2)

(1, 0, 2)

Answer 1

(1, 0, 2)

Answer 2

when they give you multiple solutions just pick one and susbtitute the values on the equation. If it fits, then you have your answer
for example:
4x + 7y – 2z = 0 , (1, 0, 2)
4(1) +7(0) -2(2) = 0
4-4 = 0
