Jawaban Terkonfirmasi

$frac{2x + 7}{ frac{5 - (x - 3)}{2} } = frac{3}{10} \ frac{2x + 7}{ frac{5 - x + 3}{2} } = frac{3}{10} \ frac{2x + 7}{ frac{8x}{2} } = frac{3}{10} \ frac{(2x + 7 )times 2}{8x} = frac{3}{10} \ frac{4x + 14}{8x} = frac{3}{10} \ 10(4x + 14) = 3(8 - x)\ 40x + 140 = 24 - 3x \ 40x + 3x = 24 - 140 \ 43x = - 116 \ x = - frac{116}{43}$
