Her next step is to find a common denominator. Remember that if you multiply a number to the denominator, you'll have to multiply it to the numerator too:

1/3(4/4) + 1/4(3/3)

4/12 + 3/12

Simplify. Combine like terms

4/12 + 3/12 = 7/12

7/12 will be final solution

hope this helps

Given that f(x) = 5x - 10 and g(x) = x + 3, find f(g(-1)).

$\bf \begin{cases} f(x) = 5x-10\\ g(x) = x + 3 \end{cases} \\\\[-0.35em] ~\dotfill\\\\ g(-1)=(-1)+3\implies \boxed{g(-1) = 2} \\\\\\ f(~~g(-1)~~)\implies f\left( \boxed{2} \right) = 5(2)-10\implies \stackrel{f(~g(-1)~)}{f(2)}=0$
