Answer:

Step-by-step explanation:
Notice that in the second equation, the coefficient of
is
times greater than in the first. Therefore, by making the coefficient of
in the second equation
times greater than in the first, it's impossible to only isolate one variable.
Therefore, when
, there are no solutions to this system.
20% * 300 = 2 * (10% * 300) = 2*30 = 60
Answer: Isolate the variable by dividing each side by factors that don't contain the variable.
