Answer:

Step-by-step explanation:

- x - 3y = - 9

- x = - 9 + 3y

x = 9 - 3y let this be the first equation

4x - 3y = -59

substitute value of x from first equation

4(9 - 3y) - 3y = -59

36 - 12y - 3y = -59

36 - 15y = -59

-15y = -59 - 36 = - 95

y = -95/ -15

y = 19/3

substitute value of y in equation 1

x = 9 - 3(19/3)

x = 9 - 19 = -10

hope this helps
