Which ordered pair is a solution to the system of linear equations One-half x minus three-fourths y = StartFraction 11 Over 60 EndFraction and Two-fifths x + one-sixth y = StartFraction 3 Over 10 EndFraction? (one-fifth, negative two-thirds) (one-fifth, two-thirds) (two-thirds, negative one-fifth) (two-thirds, one-fifth)

Step-by-step explanation:

Given the system of two equations:

Multiply the first equation and the second equation by 60 to get rid of fractions:

Now multiply the first equation by 4 and the second equation by 5:

Subtract them:

Substitute it into the first equation:

The solution is

step-by-step explanation:

so first find out how much each is worth.

quarter= 25 cents

dime= 10 cents

pennies= 1 cent

then multiply each by how much each is worth.

200                     150                   300

x                         x                     x   1

  25                       10              

                                  300

1000                     1500

+                          

4000                                      

5000                                  

then count 2 from the back and add a period.

$50.00

$15.00

$3.00

and then add them

  $50.00

+

  $15.00

+

    $3.00

$68.00

so sunghee has $68.00
