which equation 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=-2+2y+8.3
d)2/5y=2.3+3/2y

The equation which has infinite many solutions is:

                     Option: C

          C.  

An equation is said to have infinite many solution if the equation holds true for infinite many values of y.

A)

On solving for the equation we have:

Hence, we get a unique solution.

B)

On solving this equation:

Hence, we get a unique solution.

C)

Hence, the equation is true for infinite many values of y.

Hence, the equation has infinite many solution.

D)

i.e.

Hence, again we get a unique solution.

65°

step-by-step explanation:

the total measure of a triangle is 180 degrees. 62 + 53 is 115.

180 - 115 = 65
