\boxed{The\:value\:of\:x\:is\:7.375.}


\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\orange{:}}}}}


(4x - 5)2 = 49 \\ ⇢8x - 10 = 49 \\⇢8x = 49 + 10 \\ ⇢8x = 59 \\ ⇢x = (59)/(8) \\ ⇢x = 7.375

Therefore, the value of x is 7.375.


{ \bf{ \underbrace{To\:verify :}}}


(4x - 5)2 = 49 \\ ⇢(4 * 7.375 - 5)2 = 49 \\ ⇢(29 .5 - 5)2 = 49 \\ ⇢24.5 * 2 = 49 \\ ⇢49 = 49 \\ ⇢ L.H.S.=R. H. S

Hence verifed.
