Answer:

The solution is x = -3, y = 4.

Step-by-step explanation:

2x + 3y = 6

2x + y = -2

This  one ius quite straight forward to solve using elimination.

As 2x is common to both equations we can eliminate  2x by subtraction:

0 + 3y- y = 6 - (-2)

2y = 8

y = 4.

Next, we plug y = 4 into the first equation:

2x + 3(4) = 6

2x = 6 - 12

2x = -6

x = -3.

Answer:

x=-3

y=4

Step-by-step explanation:

2x+3y=6

2x+y=-2

solve for y

y=-2-2x

substitute

2x+3(-2-2x)=6

simplify

2x-6-6x=6

2x-6-6x+6=6+6

-4x=12

x=-3

substitute x

2(-3)+y=-2

-6+y=-2

y=4

Rewrite the following in ascending order.<br>9/25, 2/5, 14/-75, -19/10, 8/15​
madam [21]

Step-by-step explanation:

Given numbers are 9/25 ,2/5, 14/-75, -19/10, 8/15

The denominators = 25 , 5, 75, 10, 15

LCM of the denominators = 150

9/25 = (9/25)×(6/6) = 54/150

2/5 = (2/5)×(30/30) = 60/150

14/-75 =(-14/75)×(2/2) = -28/150

-19/10 = (-19/10)×(15/15) = -285/150

8/15 = (8/15)×(10/10) = 80/150

Ascending order of the numbers

= -285/150, -28/150, 54/150, 60/150, 80/150

<em>-19/10, 14/-75, 9/25, 2/5, 8/15</em>

Kaitlyn creates an architectural blueprint of a rectangular dining room.The area of the actual dining room is 900 times as large
katen-ka-za [31]
120 inches.

This is because to find the scale factor, you have to take the square root of the area scale. This will give you 30-1 ratio. Then multiply the 4 by that number.
