Please solve these two questions

Question 4

Simplifying the expression we get and x≠9 or x≠2

Option D is correct option.

Question 5

Simplifying the expression: we get

Option C is correct.

Step-by-step explanation:

Question 4

Simplify completely

For simplifying the above expression we have to find find factors of numerators and denominators

First finding factors of numerator

So, the factors of are

Now finding factors of denominator

So, factors of

Now, replacing numerators and denominators with their factors

so, simplifying the expression we get and x≠9 or x≠2

Option D is correct option.

Question No 5

Simplify the expression:

For simplifying the above expression we have to find find factors of numerators and denominators

First finding factors of numerator

Taking 8 common:

So, factors of are

Now finding factors of denominator :

Now, replacing numerators and denominators with their factors

So, simplifying the expression: we get

Option C is correct.

f = 4

Step-by-step explanation:

We start by re organizing the equation so all the numbers and variables that includes f, goes to the left side of the equation, while the rest of the numbers go to the right.

-11f = 7 - 14f + 5

-11f + 14f = 7 + 5

3f = 12

f = 4

I hope you get this now :] If you need any more clarification, feel free to ask me!
