\huge {\pink {\mathfrak{Solution:-}}}

Let the required number be x.

Atq,

\implies( x \times \dfrac{2}{3}) + 19  = 29 \\  \\  \implies  \dfrac{2x}{3} + 19  = 29 \\  \\  \implies  \dfrac{2x}{3}  = 29 - 19 \\  \\  \implies  \dfrac{2x}{3} =  10 \\  \\  \implies 2x = 3 \times 10 \\  \\  \implies x =  \dfrac{3 \times 10}{2}  \\  \\  \implies x = 3\times 5 \\ \\  \implies x = 15

\green {\therefore{\tt {The\:required\:number\: is\:15.}}}

\underline{\bold {Verification:}}

\implies (15 \times  \dfrac{2}{3})  + 19 = 29 \\ \\   \implies (5 \times 2) + 19 = 29 \\  \\  \implies 10 + 19 = 29 \\  \\   \implies 29 = 29
