Answer:
The numbers are a) 10 and 2 and b) 160 and -20. Please mark me as brainliest.
Step-by-step explanation:
a) Let the numbers be x and y
x + y = 12 ...1
x - y = 8 ...2
x + x + y - y = 12 + 8 (Adding 1 and 2)
2x = 20
x = 10
10 + y = 12 (from 1)
y = 12 - 10 = 2
b) Let the numbers be x and y
x + y = 140 ...1
x - y = 180 ...2
x + x + y - y = 140 + 180 (Adding 1 and 2)
2x = 320
x = 160
160 + y = 140 (from 1)
y = 140 - 160 = -20
