-3x+9y=-12 please answer both with work will give brainliest if answered quickly 3x-4y=2

5x-7y=5
-2x+6y=-2

x=4+3y

x= ​2(1+2y) /3

x=1+ ​7y /5

​x=1+3y

Step-by-step explanation:

(The first one)

-3x+9y=-12

−3(x−3y)=−12

x−3y= ​−12 /-3

x−3y= ​12/​3

x−3y=4

x=4+3y

(The second one)

3x-4y=2

3x=2+4y

x= ​2+4y /​3

x= ​2(1+2y) /​3

(The third one)

5x-7y=5

5x=5+7y

x= ​5+7y /5

​​x=1+ ​7y /5

(The fourth one)

-2x+6y=-2

−2(x−3y)=−2

x−3y=1

x=1+3y

Hope this helps you :)

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
