(6,-1)
Multiply each equation by the value that makes the coefficients of xx opposite.(−3)⋅(2x+6y)=(−3)(6)(-3)⋅(2x+6y)=(-3)(6)(2)⋅(3x−2y)=(2)(20)(2)⋅(3x-2y)=(2)(20)Simplify.−6x−18y=−18-6x-18y=-186x−4y=406x-4y=40Add the two equations together to eliminate xx from the system.Divide each term by −22-22 and simplify.Tap for more steps...y=−1y=-1Substitute the value found for yy into one of the original equations, then solve for xx.Tap for more steps...x=6x=6The solution to the independent system of equations can be represented as a point.(6,−1)

Answer from: innocentman69

solution is (6,-1)

Step-by-step explanation:

2x + 6y = 6

3x – 2y = 20

WE use elimination method to solve for x and y

Multiply the second equation by 3

3x – 2y = 20 times 3

9x – 6y = 60

2x + 6y = 6 , add both equations

------------------------------

11x = 66

Divide both sides by 11

x=6

Plug in 6 for x in first equation

2x + 6y = 6

2(6) + 6y = 6

12 + 6y = 6 , subtract 12 on both sides

6y = -6

divide both sides by 6

y=-1

$x=6 \ and \ y= -1$

Answer from: Quest

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq and the angle ∠orq are opposite, therefore:

$m\angle opq+m\angle orq=180\°\\\\m\angle opq+ (2x + 16)\°=180\°$

then, $m\angle opq+ (2x + 16)\°=180\°$ can be used to d to calculate the measure of ∠opq

Quadrilateral opqr is inscribed in circle n, as shown below. which of the following could be used to
