Answer 2

Answer:

Question :-

$\leadsto \tt{\dfrac{5x + 1}{2} - \dfrac{x - 2}{6} =\: \dfrac{2x + 4}{3}}$

To Find :-

• What is the value of x.

Solution :-

$\bigstar\: \: \sf\bold{\purple{\dfrac{5x + 1}{2} - \dfrac{x - 2}{6} =\: \dfrac{2x + 4}{3}}}$

$\longrightarrow \bf \dfrac{5x + 1}{2} - \dfrac{x - 2}{6} =\: \dfrac{2x + 4}{3}$

$\longrightarrow \sf \dfrac{3(5x + 1) - 1(x - 2)}{6} =\: \dfrac{2x + 4}{3}$

$\longrightarrow \sf \dfrac{15x + 3 - x + 2}{6} =\: \dfrac{2x + 4}{3}$

$\longrightarrow \sf \dfrac{15x - x + 3 + 2}{6} =\: \dfrac{2x + 4}{3}$

$\longrightarrow \sf \dfrac{14x + 5}{6} =\: \dfrac{2x + 4}{3}$

By doing cross multiplication we get,

$\longrightarrow \sf 3(14x + 5) =\: 6(2x + 4)$

$\longrightarrow \sf 42x + 15 =\: 12x + 24$

$\longrightarrow \sf 42x - 12x =\: 24 - 15$

$\longrightarrow \sf 30x =\: 9$

$\longrightarrow \sf x =\: \dfrac{\cancel{9}}{\cancel{30}}$

$\longrightarrow \sf x =\: \dfrac{3}{10}$

$\longrightarrow \sf\bold{\red{x =\: \dfrac{3}{10}}}$

${\small{\bold{\underline{\therefore\: The\: value\: of\: x\: is\: \dfrac{3}{10}\: .}}}}$
