Question

Simplify for Y. 9y^3=-21-3x

Answer 1

Simplifying for y we get $y=-\sqrt[3]{\frac{(7+x)}{3}}$

Step-by-step explanation:

We need to solve for the value of y

$9y^3=-21-3x$

Taking -3 common on right side of equation

$9y^3=-3(7+x)$

Dividing both sides of equation by 9

$y^3=-\frac{3(7+x)}{9}$

$y^3=-\frac{(7+x)}{3}$

Taking cube root on both sides:

$\sqrt[3]{y}=-\sqrt[3]{\frac{(7+x)}{3}}\\ y=-\sqrt[3]{\frac{(7+x)}{3}}$

So, Simplifying for y we get $y=-\sqrt[3]{\frac{(7+x)}{3}}$
