\huge\mathcal{\fcolorbox{cyan}{black}{\pink{ANSWER}}}

2x = 15 +  \frac{1}{2} x \\  \\  = 2x -  \frac{1}{2} x = 15 \\  \\  =  \frac{4x - 1x}{2}  = 15 \\  \\  =  \frac{3x}{2}  = 15 \\  \\  = 3x = 15 \times 2 \\  \\  = 3x = 30 \\  \\ x =  \frac{30}{3}  \\  \\ x = 20

verification

2(10) = 15 +  \frac{1}{2} (10) \\  \\  = 20 = 15 + 5 \\  \\ 20 = 20 \\  \\ (rhs = lhs) \\  \\ hence \: proved

hope its helpful ⭐✨
