R / (r + g) = 1/5 === 5r = r + g === 4r = g
<span>(r + 5) / (r + 5 + g) = 1/3 --- 3r + 15 = r + 5 + g </span>
<span>2r = g - 10 ... 4r = 2g - 20 </span>
<span>g = 2g - 20 </span>
<span>g = 20 .... 4r = g ... r = 5 </span>
<span>20 green and 5 red </span>
<span>4x(5y-x)-5y(4x-y)=20xy-4x^2-20yx+5y^2=-4x^2+5y^2=5y^2-4x^2</span>
Answer:
(-1,3)
y=5x+8 , y=-4x-1y=5x+8,y=−4x−1
Both sides have y on the left hand side so make the right hand side equal and solve for x
5x+8= -4x-15x+8=−4x−1
To solve for x , add 4x on both sides
9x+8=-19x+8=−1
Subtract 8 on both sides
9x=-99x=−9
Divide by 9 on both sides
x=-1x=−1
Now plug in -1 for x in the first equation and find out y
y=5x+8y=5x+8
y=5(-1)+8y=5(−1)+8
y=-5+8y=−5+8
y=3y=3
Ordered pair is (x,y) that is (-1,3)
