Question

brand A has a recognition value worth 43 billion more than brand B if the total value of these two brands is 109 billion find the value of each of the brands

Answer 1

This can be solved by systems of linear equations. This problem asked us to find values for brand A and B. As a rule of thumb, the number of unknowns must equal to the number of independent equations. First equation is A = B +43billion and the second is A + B = 109billion. Solve these equation simultaneously you should get:
A=76 billion
B = 33 billion.
