Answer:

Step-by-step explanation:

A) When the first equation is multiplied by 5 and the second equation by –6 ,

the equations become,

35x + 60y=54

-30x - 60y=60

Hence we can eliminate y by adding the equation.

B)  When the first equation is multiplied by -5 and the second equation by 6 ,

the equations become,

-35x - 60y=54

30x + 60y=60

Hence we can eliminate y by adding the equation.

C)  When the first equation is multiplied by -5 and the second equation by 7,

the equations become,

-35x  - 60y=54

35x - 70y=60

Hence we can eliminate x by adding the equation.

D) When the first equation is multiplied by 5 and the second equation by -7,

the equations become,

35x  + 60y=54

-35x - 70y=60

Hence we can eliminate x by adding the equation.

E) When the first equation is multiplied by -5 and the second equation by 10,

the equations become,

-35x  - 60y=54

50x - 100y=60

Hence we can not eliminate x by adding the equation.

1 - For this one I am not too sure as I generally only work with values that require an unknown. This one is an unknown asking for the values to see the fraction equivalent to 3/4 however if I had to guess here it would probably be 9/12 as it asks what is equal to 3/4. 3 goes into 9 3 times and into 12 4 times so it equals 3/4. Note: 9/12 has a numerator less than the denom but so does 6/8 which is the lesser fraction and still equals 3/4.
2 - Well simply put. \frac{5}{15} =  \frac{1}{3} 
3 - For this one we have to do a bit of work.
Basically just make an equation such as n for numerator and d for denominator.
d = 2n - 4
Now all we have to do is plug in.
2 * 3 - 4 = 2 
<span>2 * 6 - 4 = 8 </span>
<span>2 * 9 - 4 = 14 </span>
<span>2 * 12 - 4 = 20 
</span>So now we know our numerator or n equals 12.
The denominator or d equals 20 so we would get the fraction of....
