Answer:

Step-by-step explanation:
Let:

We need to eliminate one of the variables, so let's use elimination method. First multiply (1) by 2

Now subtract (2) from 2*(1) in order to eliminate x:

Solving for y:
Multiplying both sides by -1  

Finally, replacing the value of y in (1)

Solving for x:
add 41 to both sides:

Multiply both sides by 1/2:

 
        
             
        
        
        
6/8 = 0.75
0.75 x 100 = 75%

<h3>What is a square?</h3>
A square is a common polygon with four equal sides and angles that are each 90 degrees in length.
A square has four equal sides, four vertices, and is a closed, two-dimensional object. It has parallel sides on either side. A square is also equivalent to a rectangle with equal length and width.
Many objects can be found in your surroundings that have a square shape. The chessboard, craft sheets, bread slice, picture frame, pizza box, wall clock, etc. are typical instances of this shape.
Specifications of a Square
It has four vertices and four sides.It has equal-length sides.Since all interior angles are equal and right angles, they are all 90° in length.360° is the total of all interior angles.Its two diagonals form a straight angle with one another.
