dimulka [17.4K]

23.44 / 20 = 1.172 rounds to 1.17 per lb <== this is cost per lb...this is telling u how much each lb of dog food costs

20 / 23.44 = 0.85....this is lbs per dollar....this is telling u that u r getting 0.85 lbs for a dollar

Solve using any method. −2x+y=−3 x+y=3 ( 5, 2) ( 1, 2) ( 2, 5) ( 2, 1)

Answer:

Therefore the solution set is (x , y) = ( 2 , 1 )

Step-by-step explanation:

Given:

$-2x+y=-3$ ...............Equation ( 1 )

$x+y=3\\$ ...............Equation ( 2 )

$\therefore y=3-x$ ...............Equation ( 3 )

To Find:

x = ?

y = ?

Solution:

Using Substitution Method we will have

Substitute above ' y ' Equation 3 in Equation 1 we get

$-2x+(3-x)=-3\\-2x-x=-3-3\\-3x=-6\\3x=6\\x=\dfrac{6}{3}=2\\\\x=2$

Now Substitute ' x ' in Equation 3 we get

$y=3-2=1\\y=1$

Therefore the solution set is (x , y) = ( 2 , 1 )
