We are given expression:
.
Tyna simplified the given expression to
.
Explanation: In order to simplify
, Tyna need to simplify rational expression
.
On dividing top and bottom by 3, we get
.
Which Tyna got correct.
Now she need to simplify
.
<em>On applying quotient rule of exponents, we need to subtract the exponents of x's.</em>
So, it would be
.
<h3>So, the final answer should be

.</h3><h3>Therefore, Tyan forgot to add exponent to x.</h3><h3>The exponent of x should be 5.</h3>

2x+3y=2
x+6y=4
Multiply equation II by II
2x+3y=2
2x+12y=8
-------------
9y=6
y=6/9
y=2/3
Solving for x by replacing in equation 1;
2x+3*2/3=2
2x+2=2
2x=0
x=0
