Question

What value of b will cause the system to have an infinite number of solutions? y=6x+b -3x+1/2v=-3

Answer 1

9514 1404 393

Answer:

-6

Explanation:

Multiply the second equation by 2 and add 6x. You get ...

-6x +y = -6

y = 6x -6

This is the same as the first equation when b = -6. That is what you want if you want infinite solutions.
