Use similar triangles (see the picture I drew at the bottom)

$\frac{6.3}{13.8} = \frac{18.9}{x} \\6.3x=(13.8)(18.9)\\6.3x=260.82\\x=41.4$

Answer:

Step-by-step explanation:

$\frac{2x - 5}{5} + x - 2 = 3(x + 5)$

$\frac{2x - 5}{5} + x - 2 = 3x + 15$

$\frac{2x - 5}{5} = 2x + 17$

$2x - 5 = 10x + 85$

$-8x = 90$

$x = \frac{-45}{4}$
