3x+5y=-3 x-5y=-5 show your work
1 answer:
We are given the equations 3x+5y=-3 and x-5y=-5.
Both equations have a 5y term which allows us to easily solve the system by elimination. To do so we will add the equations together like a simple addition problem by adding the x terms together, the y terms together, and the integer answers together.
3x + 5y = -3
+x - 5y = -5
---------------
4x + 0y = -8
The y terms cancel out since one is positive and one is negative. Now we can solve for x.
4x = -8
x = -2
Now plug -2 in for x in one of the original equations to find y.
(-2) - 5y = -5
-5y = -3
y = 3/5
Our answer as an ordered pair is (2, 3/5)

Answer:
x=4
Step-by-step explanation:
subtract 8 from both sides
then you get 2x=8
then divide by 2
then you get x=4
Answer:
There are 3060 apples in the shipment.
Step-by-step explanation:
Given:
Number of boxes of apples = 15
Each boxes contains = 17 bags of Apples
hence 15 boxes will contains = Number of bags of apples in 15 boxes.
By Using Unitary Method we get;
Number of bags of apples in 15 boxes =
Hence 15 boxes contains = 255 bags of apples.
Also Given:
Each bag contains = 12 apples
255 bags contains = Number of apples in 255 bags
By Using Unitary Method we get;
Number of apples in 255 bags =
Hence 255 bags of apples contains = 3060 apples.
Hence There are 3060 apples in the shipment.
