Given equation :
2/3 y + 15 = 9.
We need to subtract 15 from both sides first.
<h3>2/3 y + 15-15 = 9 -15 <em>Subtraction property of equality.</em></h3>
Now, we need to simplify it.
We get
<h3>2/3 y = - 6 <em> simplification </em></h3>
Now, we need to get rid 2/3 from left side.
On multiplying both sides by 3/2,
<h3>2/3 y * 3/2 = - 6 * 3/2 <em>Multiplication property of equality.</em></h3>
On simplifying, we get
<h3>y = -9 <em>simplification </em></h3>
