Home team scored 9 runs in all

Let,

x=the runs scored in the first three innings

so,

\(\displaystyle\Rightarrow{x}+{x}+{5}={9}\)

\(\displaystyle\Rightarrow{2}{x}+{5}={9}\)

\(\displaystyle\Rightarrow{2}{x}={9}-{5}\)

\(\displaystyle\Rightarrow{2}{x}={4}\)

\(\displaystyle\Rightarrow{x}=\frac{{4}}{{2}}\)

\(\displaystyle\Rightarrow{x}={2}\)
