Answer:

x =y =

Explanation:

in order to solve this system of equation let us say

3x - 5y = -35...........................................................equation 1

12x+y=-6......................................................equation 2

from equation 2

12x+y=-6......................................................equation 2

y = -6 - 12x.......................................... equation 3

substitute for y = -6 -12x into equation 1

3x - 5y = -35...........................................................equation 1

3x -5( -6 - 12x) = -35

3x + 30 + 60x = -35

63x + 30 = -35

collect like terms

63x= -35 -30

63x = - 65

divide both sides by 63

63h/63 = -65/ 63

x = -1.03

put x = 1. 03 into equation 3

y = -6 - 12x.......................................... equation 3

y = -6 - 12( -1.03)

y = -6 + 12.38

y = 6.38
