Answer:

 Value \: of \: x = \frac{28}{3}

Step-by-step explanation:

 Given \: linear \: equation \: in \: one \\variable \:x \:is \: 5x-7=2x+21

/* Add both sides of the equation by 7 ,we get

\implies 5x - 7 + 7 = 2x + 21 + 7

\implies 5x = 2x + 28

/* Subtract both sides of the equation by 2x , we get

\implies 5x - 2x = 2x + 28 - 2x

\implies 3x = 28

/* Divide each term by 3, we get

 \implies \frac{3x}{3} = \frac{28}{3}

\implies x = \frac{28}{3}

Therefore.,

 Value \: of \: x = \frac{28}{3}
