What is the X and Y value?

x = 0

y = -1

Step-by-step explanation:

-6x - 4y = 4

-6x + 4y = -4

Add both equations .

We have

-12x = 0

Divide both sides by -12

-12x/-12 = 0/-12

x = 0

Substitute 0 for x in either of the equations to get y. Using equation one, we have

-6(0) - 4y = 4

-4y = 4

Divide both sides by -4 to get y.

-4y/4 = 4/-4

y = -1

x = 0, y = -1

Step-by-step explanation:

-6x - 4y = 4 (1)

-6x + 4y = -4 (2)

Adding (1) and (2)

-12x = 0

x = 0

-6x - 4y = 4

-4y = 4

y = -1

x = 0, y = -1

c is the correct answer

step-by-step explanation:

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
