laiz [17]

Answer:

y=-6 and x=0

Step-by-step explanation:

-4x -2y = -12

4x + 8y = -24

(add the equations)

6y = -36

-36/6 = -6

y=-6

(Add y value in any of the equations)

-4x-2(6) = -12

-4x-12=-12

-4x=0

scoundrel [369]

Answer:

let w = amt of water required

:

An equation based on the the percent water, an 80% solution is 20% water.

 

.20(320-w) + w = .50(320)

64 - .2w + w = 160

.8w = 160 - 64

w = 96%2F.8

w = 120 gal of water to produce 320 gal of 50% antifreeze

:

320 - 120 = 200 gal of 80% solution

Water: _120___ gallons

Premium Antifreeze: __200___ gallons
