0.5x+4/1.2x+8-5/7=0 solve using cross multiplication method​

Answer 1

$\red{\underline{\bf \: Question}} : \sf \: \green{\dfrac{0.5x + 4}{1.2x + 8} - \dfrac{5}{7}} = 0 \\ \\ \blue{\bf{solve \: by \: cross - multiplication \: method.}} \\ \\ \red{\underline{\bf solution}} : \\ \\ \sf \: \dfrac{0.5x + 4}{1.2x + 8} = \frac{5}{7} \\ \\ \bf \: cross - multiply \: now \\ \\ \red\longrightarrow \sf 7(0.5x + 4) = 5(1.2x + 8) \\ \\ \red\longrightarrow \sf \: 3.5x + 28 = 6x + 40 \\ \\ \red\longrightarrow \sf \: 6x - 3.5x = 28 - 40 \\ \\ \red\longrightarrow \sf \: 2.5x = - 12 \\ \\ \red\longrightarrow \sf \: x = \frac{ - 12}{2.5} \\ \\ \red\longrightarrow \huge\boxed{\bf \red{x} \orange{=} \pink{( - 4.8)}}$
