Subtract the 2nd row from the 1st row
5x = 5
Solve for x in the equation above
x = 1
Substitute x = 1 into any of the two equations above
Let's pick the first equation; 4x + 3y = -5
4 * 1 + 3y = -5
Solve for y in the equation above
y = -3
Therefore,
<u>x = 1</u>
<u>y = -3</u>

Step-by-step explanation:
3×2=6
The total area of the figure is 139.20 square centimeters
Areas
The area of a shape is the amount of space it occupies
<h3>Composite figure</h3>
The figure (see attachment) is a composite figure, and the total area is the sum of the areas of each shape that makes up the complete figure
The shape has 6 equilateral triangles, each of which has an area of:

Where:
--- the length of each toothpick
The area of the rectangle is then represented as:


So, the total area of the figure is:

This gives

Substitute 6 for s




Hence, the total area of the figure is 139.20 square centimeters
