$\huge{\underline{\tt{QUESTION:-}}} \\ \\ If \: 8x + \frac{21}{4} = 3x + 7 \: then \: x\: value \: is\: ? \\ \\ \huge{\underline{\tt{ANSWER:-}}} \\ \\ 8x + \frac{21}{4} = 3x + 7 \\ 8x - 3x = 7 - \frac{ 21}{4} \\ 5x = \frac{7}{1} - \frac{21}{4} \\ 5x = \frac{28 - 21}{4} \\ 5x = \frac{ 7}{4} \\ x = \frac{7}{4 \times 5} \\ x = \frac{7}{20} \\ \\ Therefore,\: the \: correct \: option \: is \: (b)$
