Answer:
x = -4
Step-by-step explanation:
x+y = -10 -------- (1)
x-y = 2 ------- (2)
from (1)
x+y = -10
y = -10-x -------- (3)
substitute (3) into (2)
x-y = 2
x-(-10-x) = 2
x+10+x = 2
2x = 2-10
2x = -8
x = -8/2
0.83333333333
you divide -12 both sides but its a really odd number
over 9000 becuz it is over 9000
the answer is 96
- 9-3
100--3
100-1-3
96
