Given a System of linear equations, the solution of the system is the point in which the lines intersect, where "x" is the x-coordinate and "y" is the y-coordinate.
Having the following System of equations:
You can use the Elimination method to find the value of "x":
-Multiply the second equation by 3.
- Add the equations.
- Solve for "x".
Then, you get:
Question 21: 24 minutes
x =
x = 24
Question 22: 20 centimeters
x = one side of the square
x² = 25
x = 5
4x = perimeter
4(5) = perimeter
20 = perimeter
Question 23: 17 sides
Hexagon = 6 sides
Octagon = 8 sides
Triangle = 3 sides
Total amount of sides = 6 + 8 + 3
Total amount of sides = 17
