Tina wrote the equations mc011-1.jpg and mc011-2.jpg. what can tina conclude about the solution to this system of equations?
(–3, 2) is a solution to the system of linear equations.
(–2, 3) is a solution to the system of linear equations.
(2, –3) is a solution to the system of linear equations.
(3, –2) is a solution to the system of linear equations.

The equations that are used to determine the values of x and y are 3x - y = 9 and 4x + y = 5. According to the degrees of freedom rule, the number of unknown variables should be equal to the number of independent equations in order to solve the problem. In this respect, we can use elimination in order to solve the equations

3x - y = 9
4x + y = 5

we add these two in order to eliminate y, thus,

7x = 14
x = 2 

from equation 1, 3*2 - 9 = y ; y = -3. hence the solution set is equal to (2,-3). The answer to this problem would have to be C.

Idon’t understand this but 90

10.4 is the answer for you
