Trystan Koch · Answer 1

First, consider the total male and female passengers which is 48. Equation 1 can be expressed as,

xx + yy = 48

Then, for the ratio,

xx / yy = 5/7

Cross-multiplying the equation. The equation becomes,

7xx = 5yy

The two linear equations are therefore,

(1) xx + yy = 48

(2) 7xx - 5yy = 0
