Answer 1

i ll tell you the equations you try solving it.
A=2O
O+B=.10 +A
2O= .15 +B

Answer 2

b. O.o?

Answer 3

substitute A in second equation
so
O + B = .10 + A
O + B = .10 +2O
B = .10 + O
now add this equation to the last equation
(B = .10 + O) + ( 2O= .15 + B)
B + 2O = .10 + .15 + O + B
O = .25
