Question

Determine which system below will produce infinitely many solutions.

2x + 5y = 24
2x + 5y = 42

3x - 2y = 15
6x + 5y = 11

4x - 3y = 9
-8x + 6y = -18

5x - 3y = 16
-2x + 3y = -7

Answer 1

infinitely many solution will be a coincident line....the same line

-8x + 6y = -18 --- reduce by dividing by 2
-4x + 3y = - 9 -- multiply by -1 to make x positive
4x - 3y = 9

same as the other equation

answer is 3rd one...they are the same line

thank you
