Answer:
y= -7 and x= -1
Step-by-step explanation:
To do this, line up the variables so it looks like this...
y-6x=-1
y-3x=-4
The reason why -6x and -3y changes to negative is because that it moved to the other side of the equation.
distribute negative to the bottom equation because the two equations have the same number variable which is y...
y-6x=-1
-y+3x=4
Y cancels out and it will be left with -3x = 3.
X = -1.... plug that in to any of the two equation and you get y = -7.
Hope I helped and have a nice day!!

It can be 1/3, 1/7, 2/7, 3/7, 1/5, 2/5, 1/13, 2/13, 3/13, 4/13, etc
The distance between point and the center (0,0) is of 9 units, which is less than the radius, hence the correct option is:
Yes, the distance from the origin to the point is of 9 units.
<h3>What is the distance between two points?</h3>
Suppose that we have two points, and . The distance between them is given by:
In this problem, we have a circle with center at (0,0) and radius 10. Hence, every point that is less than 10 units of distance from point (0,0) will be on the circle.
The distance of is:
D = 9 units.
9 < 10, hence the correct option is:
Yes, the distance from the origin to the point is of 9 units.

We got the value of by solving the given equations and by reduction method.
<h2>
What is reduction method?</h2>
The reduction or elimination approach includes using arithmetic operations between equations to produce equivalent equations with fewer unknowns that are simpler to analyze and evaluate.
Given equations are
.........(1)
...........(2)
We need to find the value of
Simplifying the given equation (2) and we get
................(3)
Now, substitute the equation (3) in equation (1) and we get
Substitute the value of x in equation (3), we get
Now adding the values of x and y, we get
Therefore, the value of .
