What is the solution of the system of equations? {-3x - 4y - 3z = -7 {2x - 6y + 2z = 3 {5x - 2y + 5z = 9 a. (5,-2,7) b. (-5,2,7) c.(5,2,-7) d. no solution use a matrix to find the solution to the system of equations. {-8x - 8y = -16 {6x - 9y = -108 ,8) b.(6,8) c.(8,-6) solve the system by elimination. {-2x + 2y + 3z = 0 {-2x - y + z = -3 {2x+ 3y+ 3z = 5 d.(6,-8)

1. D

2.A

3. (-2, 5, -2)

I hope this helps :)

the outcome of 1970 oil crisis in united states was that, they began to search ways on how to reduce oil.

in 1970 was a period when there were energy and oil crisis. those who were major centers for industrialization were forced to keep way from supplying of petroleum.

some of the result of this crisis was economic growth became stagnant because prices of oil surged.

due to the increased prices some countries like mexico and norway benefited.

the correct answer would be a. i think tara will practice for her test because she realizes her mistake

hope i .

could i get brainliest.
