Answer:
47
Step-by-step explanation:
Let us assume his son be x
So, the oliver age is x + 33
Now eight years ago, oliver age is 5 more than thrice his son present age
x - 8 = 5 + 3x
So,
33 + x = 5 + 3x
2x =28
x=14
o = 33+14 = 47
Answer: 12a=48
4a+6b=10
4a=10-6b
a=(10-6b)/4
a=(5-3b)/2
2a-4b=12
2((5-3b)/2)-4b=12
(5-3b)-4b=12
5-7b=12
-7b=7
b=-1
2a-4(-1)=12
2a+4=12
2a=8
a=4
a=4, b=-1
12a=48
the answer is b fam
