3x+2y=18
8x+6y=50
2y=18-3x
Y=9-3/2x
8x+6 (9-3/2x)=50
8x+54-9x=50
-x+54=50
X=4
Y=9-3/2 (4)
Y=9-6
Y=3

Answer:
Explanation:
The expression that you want to simplify is:
This is the simplification step-by-step:
1. Mulitply the expressions on the numerator among them and the expressions on the denominator among them:
2. For equal bases that are multiplying, add the exponents:
3. Pass the power on the denominator to the numerator by changing its sign (negative exponents become positive when inverted)
4. Simplify adding the exponents with the same base:
And that is the final expression in its most simple form.
