Answer 1

$\displaystyle 1-\frac{8x}{15}=\frac{4x}{9}\\ \\45-24x=20x\\ -24x-20x=-45\\-44x=-45\\\\x=\frac{45}{44}=1\frac{1}{44}$

Answer 2

$1-\frac{8x}{15} = \frac{4x}{9} \\\\1-\frac{8x}{15}-\frac{4x}{9}=0 \\\\\frac{45-24x-20x}{45}=0\\ \\\frac{45-44x}{45}=0 (*45)\\\\45-44x=0\\-44x=-45\\x=\frac{-45}{-44} \\\\\x=1\frac{1}{44}$
