The solution to a system of equations is the point where the 2 lines of a graph cross each other.
On the pictured graph, the lines cross each other at x = -6 and Y = -2.
The answer would be (-6,-2)
Procedures can also be called methods because they are like steps and rules that you can follow.
For this case, we observe that the triangles are similar.
We observe that the triagnules have three equal angles.
Therefore, to find the value of x we can use the following relationship:

Clearing x we have:
Answer:
The value of x is given by:
x = 6.25
To figure out the percentage of a number, take the percentage and move the decimal to the left two times. So 315 would turn into 3.15.
Now multiply the new number to the other number.
3.15 * 26.2
The answer is 82.53.
Hope this helped!
