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
