Which has infinitely many solutions?

A.) - 6.8 + 3y + 2.4 = 4.3 - 3y

B.) 1/3y + 2.5 - 2/3y = 1.2

C.) 5.1 + 2y + 1.2 = - w + 2y + 8.3

D.) 2/5y = 2.3 + 3/2y

The ones that simplify to x=x or c=c where c is a constant

as soon as you have

ax+b=c where a, b, and c are constants (and b≠0 and a≠0), then there is one solution

A. - 4.4+3y=4.3-3y

-4.4+6y=4.3

this has one solution

B. - 1/3y+2.5=1.2

this has 1 solution

C.

6.3+2y=6.3+2y

2y=2y

y=y

infinite solutions

D. 4/10y=2.3+15/10y

-11/10y=2.3

1 solution

C is the answer
