Use the distributive property to eliminate parentheses:
... = 3y -y -2x +x
Collect terms:
... = y(3 -1) +x(-2 +1)
... = 2y -x
1/3x = x - 22.
That is the equation that you use, to find the number. Subtract 1/3x from x to get 0= 2/3x -22. Yes, it is possible to have 0 on one side in certain instances. The next thing you do is add 22 to both sides to get 22= 2/3x. Finally, divide both sides by 2/3 and you get 33 = x or x = 33. If you don't believe me, substitute x for 33. 11 = 11. I hope this helps in any way, and have a nice day!
The system of equations has one solution (-1, 1)
<h3>Graph of system of linear equations </h3>
From the question, we are to graph the given system of equations.
The given system of equation is
y + 2x = −1
3y − x = 4
The graph of the given system of equations is shown below.
From the graph, we can observe that the solution to the given system of equation is given by two lines that intersect at the point (-1, 1).
Hence, the system of equations has one solution (-1, 1)

In a right triangle, the ratio of the opposite side of one angle to the hypotenuse is called sine.
In this problem the side JK is the opposite side of angle JLK whose value is 63 degrees. The hypotenuse is JL whose value is 8.
So the sine ratio of angle JLK would be
sin L=JK/JL
Substituting the numerical values,
sin 63°=JK/8
This implies JK=sin 63°×8 from wich we will get the value of JK
So, this equation sin 63°=JK/8 will let us solve for jk and the answer is the third one.
