8 A shopkeeper orders packets of soap
powder. The cost price of a large packet is
180 and that of a small packet is N80. She
is prepared to spend up to #4000 altogether
and needs twice as many large packets as
small packets with a minimum of 10 large
and 20 small packets.
a What is the greatest number of packets
she can buy?
The profit is N20 on a large packet and N10
on a small packet.
b Which arrangement gives the greatest
profit?
c What is that profit?
y 20​

chase is right because he already been to the swings and he know how far it will be to get there

step-by-step explanation:

step-by-step explanation:

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

collect results in alphabetical order:

answer:   {x = -1/2 ,   y = -1
