Answer:
49, 37
Step-by-step explanation:
Let one number be x and other be y.
According to the first condition:
x + y = 86.....(1)
According to the second condition:
x = y + 12..... (2)
Substituting x = y + 12 in equation (1)
y + 12 + y = 86
2y = 86 - 12
2y = 74
y = 74/2
y = 37
x = y + 12
x = 37 + 12
x = 49
Thus, the two numbers are 49 and 37
