Someone pls answer this it’s so confusing lol
GenaCL600 [577]

Answer:

<h2>y = \frac{w}{h -  {2c}^{3} }</h2>

Step-by-step explanation:

w = yh - 2yc³

First of all factorize y out of the expression on the right side of the equation

That's

w = y( h - 2c³)

Next divide both sides by (h - 2c³) to make y stand alone

We have

<h3>\frac{y(h -  {2c}^{3}) }{h -  {2c}^{3} }  =  \frac{w}{h -  {2c}^{3} }</h3>

We have the final answer as

<h3>y = \frac{w}{h -  {2c}^{3} }</h3>

Hope this helps you
