System of Equations Matrix

Solve for y :

3x + 4y = 52

5x + y = 30

• 10

• 4

• -10

• -4

Use matrices to solve the system of equations for the y-coordinate.

• y = -7

• y = -3

• y = 7

• x = -3

Solve for the value of the x-coordinate.

8x - 6y + 20 = 0

7y - 16x - 45 = -15

• 2

• -2

• -1

• 1

Solve the system for the value of y:

2y + 7x + 6 = -13

2y - x - 7 = 14

• y = 8

• x = -5

• y = -5

• y = -8

Solve:
-4x - 5y - z = 18
-2x - 5y - 2z = 12
-2x + 5y + 2z = 4

• (4, 0, -2)

• (-4, 0, -2)

• Many Solutions

• I did not get any of the answers above so I am assuming none of the above.
