`\large\text{Hey there!}`

`\large\text{If x = 4 then replace x with the number 4 since we found out what the}\\\text{value of x is.}`

`\large\text{The new equation is:}\mathsf{\ 2(4)^2-5}`

`\mathsf{2(4)^2-5}\\\mathsf{4^2=4*4\rightarrow\underline{\bf{16}}}\\\mathsf{2(16)-5}\\\mathsf{2(16)= \underline{\bf{32}}}\\\mathsf{32-5=\underline{\bf{27}}}\\\\\boxed{\boxed{\mathsf{Thus,\ your\ answer\ is: \boxed{\large\text{27}}}}}\large\checkmark`
