Because 19 is being divided, you have to do the opposite. What's the opposite of division? Multiplication. So multiply 19 to -7, then get rid of the 19 on the x's side(cuz it was cancelled out). Now you should have x<-133. In case you don't know, positive times negative equals negative, but negative times negative equals positive.

Answer:
(7,2)
Step-by-step explanation:
5x + 3y = 41
3x - 6y = 9
Multiply the first equation by 2
2(5x + 3y) = 41 *2
10x +6y = 82
Add this to the second equation
10x +6y = 82
3x - 6y = 9
----------------------
13x = 91
Divide by 13
13x/13 = 91/13
x=7
Now we can find y
5x+3y = 41
5(7) +3y =51
35+3y=41
Subtract 35 from each side
35-35+3y=41-35
3y = 6
Divide by 3
3y/3 = 6/3
y=2
Example: 2x+2y=8 and 3y+2x=6
Okay so u first want to put on of the equations into a y= form. So let's use 3y+2x=6. Subtract 2x from both sides. 3y=6-2x divide by 3. Y= 6-2/3x or y= -2/3x + 6. Now just plug this new equation in for Y since "y=" into the other equation.
2x + 2(-2/3x + 6) = 8.
Then you would distribute the 2 into the parenthesis and simplify to solve for x.
After you solve for x, plug x into one of the original equations to find y.
lets draw a picture of our hexagon:
then, we can rotate 60 degrees counterclockwise (or clockwise) and get the same hexagon. So, the answer is 60 degrees
