Answer:
-66, 80
Step-by-step explanation:
Let x represent the first number. Then the second number is 14-x, and the difference is ...
x - (14-x) = -146
2x = -132 . . . . . . add 14, collect terms
x = -66 . . . . . . . . the first number
14-x = 14-(-66) = 80 . . . . . . the second number
Answer:
-66 & 80
Step-by-step explanation:
Let the two numbers be x and y
x + y = 14 (1)
x - y = -146 (2)
Adding (1) & (2),
2x = -132
x = -66
y = 14 - x = 14 - (-66) = 14 + 66
y = 80
