Answer:
A = 7 and B = 4
Step-by-step explanation:
a = smaller number
b = greater number
a - b = 3 (1)
a + 2b = 15 (2)
a + 2b = 15
- a - b = 3
(-) (+) (-)
= 3b = 12
b=12 / 3
b = 4
substitute b = 4 in (1)
a - b = 3
a - 4 = 3
a = 3 + 4
a = 7
Hence a = 7 and b = 4
To recheck if the numbers are correct
a - b = 3
7 - 4 = 3
a + 2b = 15
7 + 2(4) = 15
