If x is 12xy^2 7=? so if 12xy^2=x what is y. Y=z+129 z=394. Help!

umm... try something easier what school grade are you in?
Im in 4th grade.
damn is 4th grade hard now. I graduated and I have trouble with this one.
Assuming you don't have typos:

12xy^2=x divide both sides by 12x, y^2 = x/12x = 1/12x. What is the square root of 1/12x?

Y=z+129 z=394 then Y = 394+129 = ? I assume you can add those two.

Although delayed, I hope this helps.
12xy^2=x
12y^2 = 1 (for x≠0)
y^2 = 1/12
y = ±1/√ 12
