The first step to find the value of 'x' in this expression is to calculate the product with the parenthesis term:
[tex]\begin{gathered} 4-2(x-3)=24 \\ 4-2x+6=24 \end{gathered}[/tex]Then, we need to isolate in one side of the equation the terms with the variable 'x', and in the other side the terms without the variable 'x'. Then, we can calculate the value of x:
[tex]\begin{gathered} 4-2x+6=24 \\ -2x=24-4-6 \\ -2x=14 \\ x=\frac{14}{-2}=-7 \end{gathered}[/tex]So the value of x in this expression is -7
