Please solve for y, 2x=3y
$\displaystyle 2x=3y$
You want to get y by itself
In order to do this you must take the inverse of the coefficient and multiply it by the other side.
$\displaystyle (2x)\frac{1}{3}=y$
Since your multiplying, 2x can go on the numerator.
$\displaystyle \frac{2x(1)}{3}=y$]
anything multiplied by 1 is it's self.
inverse- The number that if multiplied to the original equals 1.
coefficient- The number, not the exponent.
numerator- top part of a simple fraction
