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

hmmm u see multiply eqn 2 from -1 and add it to eqn 3 ..... x gets eliminated..u will be havng 2 equations in y and z...... then can solve them to get y and z

Answer 2

it is d correct??

Answer 3

hmmmm plug the values in each eqns and see if it satisfies :))

Answer 4

alright thanks!
