Answer:

1/5

Step-by-step explanation:

.7555555(repeating )

writing as a fraction

x = .755555555

10 x = 7.555555

Subtract the two

10x = 7.555555

-x = .75555555

--------------------------

9x =6.8

Divide each side by 9

x = 6.8/9

x = 68/90

Divide by 2

x = 34/45

We do the same for .555555 repeating

y = .5555 repeating

10 y = 5.5 repeating

10y = 5.5

-y = .555

-------------------

9y = 5

y = 5/9

Subtract x - y

34/45 - 5/9

Get a common denominator

34/45 - 25/45

9/45

1/5

Answer:

Step-by-step explanation:

$\left\{\begin{array}{ccc}10x+2y=64&\text{multiply both sides by 2}\\3x-4y=-36\end{array}\right\\\underline{+\left\{\begin{array}{ccc}20x+4y=128\\3x-4y=-36\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad23x=92\qquad\text{divide both sides by 2}\\.\qquad x=4\\\\\text{put the value of x to the first equation:}\\\\10(4)+2y=64\\40+2y=64\qquad\text{subtract 40 from both sides}\\2y=24\qquad\text{divide both sides by 2}\\y=12$
