Answer:

-16/5

Step-by-step explanation:

Perform the indicated multiplication.  We get:

7x + 7 = 1 - 10 + 2x.

Next, combine like terms:  combine the x terms and combine the constants:

5x = -16

Dividing both sides by 5, we get the solution   x = -16/5

Simply the rational expression.state any restrictions on the variable. k2-k-2/k2-4k-5
hjlf

We are given

\frac{k^2-k-2}{k^2-4k-5}

Firstly, we will factor numerator and denominator

\frac{k^2-k-2}{k^2-4k-5}=\frac{(k-2)(k+1)}{(k-5)(k+1)}

Restrictions:

we know that denominator can not be zero

so, we can set denominator =0

and solve for k to get restrictions

(k-5)(k+1)=0

k=-1,k=5

Simplification:

\frac{k^2-k-2}{k^2-4k-5}=\frac{(k-2)(k+1)}{(k-5)(k+1)}

we can see that k+1 gets cancelled

so, we get

\frac{k^2-k-2}{k^2-4k-5}=\frac{(k-2)}{(k-5)}..........Answer
