X + 2y = 13 -x + y = 5

Mathematics
1 answer:

Answer:

x = 1; y = 6

Step-by-step explanation:

x + 2y = 13

-x + y = 5

Add the equations to eliminate x.

3y = 18

Divide both sides by 3.

y = 6

Now substitute y with 6 in the first equation.

x + 2(6) = 13

x + 12 = 13

Subtract 12 from both sides.

x = 1

Answer: x = 1; y = 6

Answer:

%30 off is the better price

Step-by-step explanation:

firstly we know that 2 - 12 is equal to 10 so that is $10.00 there from that coupon

to find out the second value, we first devide by the total amount (%100 in this case)

<em>12 / 100 = 10.12</em>

then we multiply by the partial amount (%30)

<em>0.12 * 30 = 3.6</em>

convert that into a dollar amount and we get the total discount in dollars

<em>3.60 = $3.60</em>

AND

<em>$3.60 > $2.00</em>

<em />

hope this helps ya, take care mate :D
