A woman went marketing for sugar for canning. In one store, sugar was 8 1/2¢ per pound and she found that she lacked 30¢ of havi
alex41 [277]
X=amount of money woman has
n=pounds of sugar 
Store #1: 8.5*n=x+30
Store #2: 8*n=x-25

multiply #2 by 17/16 to make coefficient of n same as in #1

2: 8.5*n=17/16(x-25)

Subtract #2 from #1

0=x+30-17/16(x-25)
x+30-17x/16 +25*17/16
x/16=30+25*17/16
x=480+425
=905 cents
=$9.05

Solve independent system equations for: <br><br>5x-9y=-65<br>10x-3y=20<br>x=?<br>y=?<br>​
Sergio039 [100]
5x-9y=-65
10x-3y=20

Multiple the first equation by 2
10x-18y=-130
10x -3y=20
Then subtract the two equations to get rid of the x

21y=-150
Divide the -150 by 21
Y=-7.14

Plug the y into the original equation. (Either one)

5x-9(-7.14)=-65
5x-64.28=-65
Then add 64.28 to the -65
5x=-0.72
Divide by 5
X=-0.144

I hope this is right
