A=2+2 as a is equal to 2 so 2+2=4 and 3+3 as b=3 so 3+3=6 so 6-4 = 2 is the answer
B=5-2+2+3 as a=2 b=3 so 2+2+3=8 so 8-5=3 is the answer
B=5-2+2+3 as a=2 b=3 so 2+2+3=8 so 8-5=3 is the answer

Answer:
The value of (a) 2a -3b is - 5 and (b) 5 - 2ab is _7
Step-by-step explanation:
Given:
a=2 , b = 3
(a) 2a - 3b=2 × a - 3 × b
putting the value of a and b we get,
= 2 × 2 - 3 × 3
= 4 - 9
= - 5
(b) 5 - 2 a b =5 - 2 × a × b
Putting the value of a and b we get,
= 5 - 2 × 2 × 3
= 5 - 12
= - 7
