Mathematics

Mrrafil [7]3 years ago

Answer:

\frac{y-2}{4}

Step-by-step explanation:

Let's start by factoring everything:

\dfrac{\frac{y^2+y}{y^2-2y}}{\frac{4y+4}{y^2-4y+4}}=

\dfrac{\frac{y(y+1)}{y(y-2)}}{\frac{4(y+1)}{(y-2)^2}}=

Now, you can cancel out some terms:

\dfrac{\frac{y+1}{y-2}}{\frac{4(y+1)}{(y-2)^2}}=

Now, when you divide a fraction by another fraction, that is the same as multiplying the first fraction by the reciprocal of the second one:

\frac{y+1}{y-2}\cdot \frac{(y-2)^2)}{4(y+1)}=

\frac{y-2}{4}

Hope this helps!

Mrrafil [7]

Answer:

x = -2, y = -8

Step-by-step explanation:

13(y + 6) - 6y = 22

=> 13y + 78 - 6y = 22

=> 7y = -56

=> y = -8

x = -8 + 6

=> x = -2
