The solutions to the given system of equations are x = 4 and y = -9
<h3>Simultaneous linear equations</h3>
From the question, we are to determine the solutions to the given system of equations 
The given system of equations are 
-8x-4y=4  --------- (1)
-5x-y=-11   --------- (2)
Multiply equation (2) by 4
4 ×[-5x-y=-11 ]
-20x -4y = -44  -------- (3)
Now, subtract equation (3) from equation (1)
-8x -4y = 4  --------- (1) 
-(-20x -4y = -44)  -------- (3)
12x = 48
x = 48/12
x = 4
Substitute the value of x into equation (2)
-5x -y = -11
-5(4) -y = -11
-20 -y = -11
-y = -11 + 20
-y = 9 
∴ y = -9
Hence, the solutions to the given system of equations are x = 4 and y = -9

Correct option is C. There are 20 ordered pairs.
Given that ordered pairs (x,y) 
such that x is even integer where 4≤x≤10 and y is an integer. 
where 4<y<10.
Then even integer 4≤x≤10 are four i:e
4,6,8,10
And integer 4<y<10 are five i:e
 5,6,7,8,9
Then ordered pair are = 4×5=20
<h3>What are ordered pairs?</h3>
An ordered pair is a composition of the x coordinate (abscissa) and the y coordinate (ordinate), having two values written in a fixed order within parentheses. It helps to locate a point on the Cartesian plane for better visual comprehension. The numeric values in an ordered pair can be integers or fractions.
