We can solve this by elimination, in order to do this we need to multiply the bottom equation by three to cross out the X

(x+5y=38)3 3x+15y=114

-3x+4y=95
3x+15y=114

then add the two equations together and the X will cancel out

19y=209
-----  -----
19     19

y=11

then plug that in into one of the equations

x+55=38
  -55   -55

x= -17

your answer is (-17,11)

Given that 8x – 3y = 36
Vedmedyk [2.9K]

Answer:

x = 45/8

Step-by-step explanation:

8x – 3y = 36

Let y=3

8x – 3*3 = 36

8x - 9 = 36

Add 9 to each side

8x -9+9 = 36+9

8x = 45

Divide each side by 8

8x/8 = 45/8

x = 45/8

Inez waters her plants every two days. She trims them every 15 days. She did both today. When will she do them both again?
shtirl [24]

The answer is 30 days.

The solution for this is to find the least common multiple. By getting the multiple of both numbers.

Multiples of 2:  2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40…..

Multiples of 15: 15,30,45,60,75……..

The Least Common Multiples of 2 and 15 is 30. So, Inez will do them both again in 30 days.

The least common multiple (LCM) of two numbers is the smallest number that is multiple by the both number.

Use elimination to solve<br><br> 3y-6x=7-4y-3x=9
Masja [62]
Reorder both sides

3y-6x=9
7-4y-3x=9

Multiply both sides
-6x-3y=9
6x+8y=-4

Dived both sides

11y= 5

Y=5/11

Substitute the value of Y

-3x-4(5/11)

Equals —> -14/11

Answer : (5/11 , -14/11)

Can someone give me the answer and explanation
DENIUS [597]

Answer: A

Step-by-step explanation:

The total minus the cost of the eggs leaves you with just the total of the potatoes. Since we know that the total of the potatoes is the product of 5 bags, we can divide the total of the potatoes by 5 to find the cost of each bag of potatoes.
