To eliminate a cariable in a system of equations, we multiply the variable by a factor that will make both coefficients of the variable to be equal.
Thus, we multiply the coefficient of y in the second equation by a factor that will make it equal to the coefficient of y in the first equation. i.e. multiply 1/2 by a factor that makes it equal to 3/4. and the factor is 3/2.
Therefore, the third option is the correct answer.
Answer:
yes

Step-by-step explanation:
(Interpreting equation as)
We can reduce the fraction by dividing the top and the bottom by terms they have in common.
First, lets rewrite both the numerator and denominator in terms of each other.
If you expand the fraction, you will get exactly what you start with, now this is fine.
As we can see both halves of the fraction have a common term (
), so we can divide by this - and the fraction will still be equivalent to as it was before
, or simplified further,
