Solve for a and b :
`2^(a) + 3^(b) = 17` and `2^(a+2) - 3^(b+1) = 5`

Solve for a and b when 2a+3b=(17)/(5),5a+b=2

Solve: (11)/(a +b) + 2 (a -b) = 11, (22)/(a +b) + 3(a -b) = 17

Solve for matrics A and B , where 2A + B = [{:( 3,-4),(2,7) :}] and A - 2B =[{:( 4,3),(1,1):}]

If (3a+2b) : (5a+7b) = 1:2 , then find a : b.

If a o+ b = a^3 + b^2 + 1 a © b = (a - b)^2 + 1 a ** b = a^3 - b^2 + 1 If P = (2 o+ 3)© (3 ** 5) , then the value of P is :

Solve : 3a+5b=-9 , 2a+5b=-11 .

Find the values of a and b, when: (i) (a+3,b-2)=(5,1) (ii) (a+b,2b-3)=(4,-5) (iii) ((a)/(3)+1,b-(1)/(3))=((5)/(3),(2)/(3)) (iv) (a-2,2b+1)=(b-1,a+2)
