\qquad \qquad\huge \underline{\boxed{\sf Answer}}

Let's solve for x ~


\qquad \sf  \dashrightarrow \: 5(2x + 4) = 15


\qquad \sf  \dashrightarrow \: (5 * 2x) + (5 * 4) = 15


\qquad \sf  \dashrightarrow \: 10x + 20 = 15


\qquad \sf  \dashrightarrow \: 10x + 20 - 20 = 15 - 20


\qquad \sf  \dashrightarrow \: 10x = - 5


\qquad \sf  \dashrightarrow \: (10x)/(10) = ( - 5)/(10)


\qquad \sf  \dashrightarrow \: x = - ( 1)/(2)

hence value of x is - 1/2
