Ava's Age Calculation

Medium Heart Of Algebra Linear Equations And Inequalities

Emily is twice as old as her sister Ava. If the sum of their ages is 30 years, how old is Ava?

Let Emily's age be represented as $E$ and Ava's age as $A$. Thus, we can establish the following equations:

1) $E = 2A$

2) $E + A = 30$

Using these equations, solve for Ava's age.
