a system of equations is shown below: x y = 3 2x − y = 6 the x−coordinate of the solution to this system of equations is _____.
pychu [463]
If you would like to solve the system of equations x + y = 3 and 2x - y = 6, you can do this using the following steps:

<span>x + y = 3 ... y = 3 - x
2x - y = 6
</span>_________
<span>2x - y = 6
</span>2x - (3 - x) = 6
2x - 3 + x = 6
3x = 6 + 3
3x = 9     /3
x = 9/3
x = 3

<span>y = 3 - x = 3 - 3 = 0
</span>
The correct result would be x = 3.

( There are two similar triangles on the graph below. Use the graph to answer the questions. You must answer each question AND e
Evgen [1.6K]

Answer:

The Slope of both the lines is the same.

Step-by-step explanation:

Given two co-ordinates (x1, y1) and (x2, y2), the slope of a line can be found using the formula:

slope = \frac{y2-y1}{x2-x1}

For the diagonal line of the first triangle, the coordinates are (0, 0) and (2, 1)

slope of diagonal line of first  triangle = \frac{1 - 0}{2 - 0} = \frac{1}{2}

For the diagonal line of the large triangle, the coordinates are (2, 1) and (6, 3)

slope of diagonal line of second  triangle = \frac{3-1}{6-2} = \frac{2}{4} = \frac{1}{2}
