Make an equation system based on the problem
<span>An equation for "A plane has 360 total seats, </span>which are divided into economy class and business class" is
∴ e + b = 360   (first equation)
"<span>For every 13 seats in economy class, there are 5seats in business class" that means in 1b there is (5/13) e
</span>∴ b= \frac{5}{13} e    (second equation)
<span>
Solve the equation, find the value of e
</span><span>Subtitute b with (5e)/13 in the first equation
</span>e + b = 360
e + \frac{5e}{13} = 360
Equalize the denominators
\frac{13e}{13} + \frac{5e}{13} =360
\frac{18e}{13}=360

move 13 to the right side, and solve for e
\frac{18e}{13}=360
18e = 360 × 13
18e = 4,680
e = 4,680/18
e = 260

Find the value of b
e + b = 360
260 + b = 360
b = 360 - 260
b = 100

There are 260 seats in economy class and 100 seats in business class
