In the pair of equations bx-6y=18 and 2x-3y=9, b is a constant. The system of two equations has infinitely many solutions. What is the value of b.
A.3
B.4
C.5
D.6

Answer 1

so do you know what it the question is trying to tell you when it says it has infinitely many solutions?

Answer 2

you can change the equations to y=mx+b. Make them equal: E1=E2. And plug in b for each choice and see which one gives to something like x=x, You can look at this website: http://www.charleston.k12.il.us/cms/Teachers/math/PreAlgebra/paunit5/L5-4.pdf

Answer 3

Ok. Thnx

Answer 4

And infinitely many solutions means more than obe solution
