Answer:
=53
Step-by-step explanation:
a=5-b &. a=9+b
combine
5-b=9+b
-4=2b
b= -2
thus, a=7
(-2)^2 + (7)^2
4+49
=53

Answer : 3²+2²=13.
Step-by-step:
Ok …according to the question
a+b=5–(1)considering it as eqn 1
a-b=9—(2)considering it as eqn 2
Substracting eqn 2 from eqn 1 we get
2b=4
b=4/2
b=2
Now substituting this value of b in eqn 1 we get
a+2=5
So a=5–2
a=3
So a=3and b=2
