Ответ:
the correct question is
what value of b will cause the system to have an infinite number of solutions?
for
y = 6x – b and -3x+(1/2)y=-3
we have that
y = 6x – b > equation 1
-3x+(1/2)y=-> -6x+y=- > -2x+y=- > y=6x-6
y=6x-> equation 2
we know that
for the system to have an infinite number of solution, equation 1 must be equal to equation 2
so
6x – b=6x-> 6x-6x=b-> b=6
the answer is b=(6)
