Correct the error in this equation:

6(2y+6)=4(9+3y)
12y+36=36+12y
12y=12y
0=0
y=0

So what’s the answer?

after 12y+36=36+12y..

the sides are both the same
so y can equal anything

The equation is no solution.

no solution

The equation you provided is already correctly solved. It simplifies to 0=0, which means that the equation holds true for any value of y. This implies that there is no restriction on the value of y, and therefore, y can be any real number. Hence, the solution to the equation is y=0.
