<h2><u>Given</u> :</h2>

The given equations are :

\longrightarrow15b + 10g = 8640 \:  \:  \:  \:  \:   - (1)

\longrightarrow b + g = 708 \:  \:  \:  \:  \:  \:  - (2)

Let's solve for g in equation (2) :

\longrightarrow b + g = 708

\longrightarrow g = 708 - b \:  \:  \:  \:  \:  - (3)

now, let's plug value of g from equation (3) into equation (1) :

\longrightarrow15b + 10g = 8640

\longrightarrow15b + 10(708 - b) = 8640

\longrightarrow15b - 10b + 7080 = 8640

\longrightarrow5b = 1560

\longrightarrow b = 312

plugging value of b in equation (3) :

\longrightarrow g = 708 - b

\longrightarrow g = 708 - 312

\longrightarrow g =39 6

since " g " represents ground seats, number of ground seats :

=》396

And " b " represents balcony seat, therefore it is equal to :

=》312
