Given : a*b = a+2b
To Find : 2*(3*4)=
Solution:
a*b = a+2b
2*(3*4)
Lets 1st solve
3*4
a = 3
b = 4
=> 3*4 = 3 + 2(4)
=> 3*4 = 3 + 8
=> 3*4 = 11
Hence
2*(3*4) = 2 * 11
a = 2
b = 11
2 * 11 = 2 + 2(11)
=> 2 * 11 = 2 + 22
=>2 * 11 = 24
Hence 2*(3*4) = 24
it does not matter which one is solved 1st
2*(3*4)
= 2 + 2 ((3*4) )
= 2 ( 1 + (3*4) )
= 2 ( 1 + (3 + 2(4)))
= 2 (1 + 3 + 8 )
= 2 (12)
= 24
