Given:

 A=\left[\begin{array}{cc} 4 & x+2 \\ 2 x-3 & x+1 \end{array}\right]

Solution:

A = AT

\begin{aligned} &A=\left[\begin{array}{cc} 4 & x+2 \\ 2 x-3 & x+1 \end{array}\right] \\ &A^{T}=\left[\begin{array}{cc} 4 & 2 x-3 \\ x+2 & x+1 \end{array}\right] \\ &\text { So, } \\ &\qquad\left[\begin{array}{cc} 4 & x+2 \\ 2 x-3 & x+1 \end{array}\right]=\left[\begin{array}{cc} 4 & 2 x-3 \\ x+2 & x+1 \end{array}\right] \end{aligned}

x + 2 = 2x - 3
