Determine which system below will produce infinitely many solutions.

 −6x + 3y = 18
4x − 3y = 6
 2x + 4y = 24
6x + 12y = 36
 3x − y = 14
−9x + 3y = −42
 5x + 2y = 13
−x + 4y = −6

anonymous · Answer

got it C. 3x - y = 14 -9x + 3y = -42

anonymous · Answer

A:−6x + 3y = 18
4x − 3y = 6

B: 2x + 4y = 24
6x + 12y = 36

 C:3x − y = 14
−9x + 3y = −42

D: 5x + 2y = 13
−x + 4y = −6

Are we sure its C?

anonymous · Answer

C because 3x-y= 14 multiplied by -3 is -9x+3y= -42 so the equations are equal

anonymous · Answer

Solve the system of equations by substitution. What is the solution for x?

2x + y = 1
4x + 2y = −1

 x = 0
 x = 2
 There is no x value, as there is no solution.
 x can be any value, as there is an infinite number of solutions.
