Understanding and solving linear equations in three variables

• (25, -5, -5)

• (5, 10, -5)

• (5, 20, -5)

• (25, 15, -5)

Find the solution to the system.

• (-2, -3, 3)

• (-2, 3, 3)

• (2, -3, 3)

Solve the system of equations: 

• ( -2, 3, -3)

• None of these

• ( -2, -3, 3)

• ( -3, 3, -2)

3) Solve the system of linear equations.

• (3, 1, -5)

• (-3, 1, -1)

• no solution

• infinitely many solutions

• (5,-7/3,0)
  

• No Solution

• Infinite Solution

• (-5,7/3,0)

Solve!

• (2,7,5)
• (-8,7,5)
• (-8,2,5)
• (-3,2,5)

find the solution(x, y, b)

2b + x + 3y = 25

6b = 12

b + 2x = 14
