3x - 5y = - 35

12x+y=-6

x = y =

Step-by-step 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
