Problema Solution
In a certain year, solar and wind energy generation totaled 1008 trillion Btu's. Wind generated 54 trillion Btu's more than eight times that generated by solar energy. How much was generated by each source?
Answer provided by our tutors
let
s = trillion Btu's generated by solar energy
w = trillion Btu's generated by wind energy
solar and wind energy generation totaled 1008 trillion Btu's
s + w = 1008
wind generated 54 trillion Btu's more than eight times that generated by solar energy
w = 54 + 8s
by solving the system of equations
s + w = 1008
w = 54 + 8s
we find
s = 106 trillion Btu's
w = 902 trillion Btu's
