You can use the elimination method.
You can have y crossed out so you can solve for x and then have x crossed out to solve for y for instance:
X - y = 8
+
X +y =4
To have y gone we have to make it equal to y - y or in this case -y + +y
So
X - y = 8
+
X + y = 4
2x = 12
———-
2. 2
X=6
Now to find y we have x crossed out.
X-y=8
X+y=4
To have x crossed out we’d do x - x
So
X-y = 8
-
X+ y = 4
-2y = 4
————-
-2. -2
Y = -2
Since coordinates go like (x,y) the system of equations for this problem is (6, -2)

Answer:
Step-by-step explanation:
If the regular price of a T-shirt is 10 USD and the store sells off its wares at 80% of its regular price, then the price at which the store would still the aforementioned T-shirt would be 80% of its 10 USD price.
80% of $10 =
0.8 * 10 = $8
This means that the price at which the T-shirt will go for, due to the ongoing sales will be $8.
Also, being asked to find the 10% and 20% of $10 is just as simple
10% of $10 =
0.1 * 10 = $1
20% of $10 =
0.2 * 10 = $2
Therefore, the 10% and 20% of $10 is $1 and $2 respectively.
Hello!
The answer would be d = 10. Solve it like this. (v v v)
10 * 0 + 4 * d = 40 ---> 0 + 4 * 10 = 40
0 + 40 = 40
40 = 40
Hope this helps! ☺♥
Hello there! Shelly ran D) 5/10 more miles than Ben.
To find the difference between the two runner's distances, subtract the smaller distance from the greater distance.
8/10 - 3/10 = 5/10
Since there is a difference of 5/10, this means Shelly ran 5/1 more miles.
I hope this helps, & have a great rest of your day! :)
