Solve the following system of equations: -8x+3y=7 13-3y=-17 x=? y=?

x = -2 and y = -3

Step-by-step explanation:

It is given that,

-8x + 3y =7    (1)

13x - 3y =-17   (2)

To find the value of x and y

eq(1) + eq(2) ⇒

-8x + 3y = 7    (1)

13x -  3y = -17   (2)

 5x +    = -10

x = -10/5 = -2

Substitute value of x in eq (1)

-8x + 3y =7    (1)

-8 * -2  + 3y = 7

16 + 3y = 7

3y = 7 - 16 = -9

y = -9/3 = -3

Therefore x = -2 and y = -3

For this case we must solve the following system of equations:

If we add both equations we have:

We find the value of the variable "y":

Thus, the solution of the system is (-2, -3)

(-2, -3)

the answer is c
