Answer:

$x = 5$

$y = - 5$

Step-by-step explanation:

Look at the second equation.

Add 6y to both sides:

$- 6x = 6y$

Hence,

$y = - x$

Substitute this into first equation:

$- 4x - x = - 25$

$- 5x = - 25$

$x = 5$

Since y = -x,

$y = - 5$

the selling price for a refrigerator is 584 if the mark up is 25% of the dealers cost, what is the dealers cost of the refrigera

tia_tia [17]

25% of 584 is 146. If you meant to say "25% off of the dealer's cost", the answer would be $438, since you're finding what 25% of the original price is (146) and subtracting it from the original price. The equation would be 584 - 146 = 438. I hope this helped <3
