Answer :
Find the value of the following expression when x=3:
The objective of solving expressions, is to find the outcome value of a certain x-value, for example in this expression:
[tex]\begin{gathered} \frac{2x}{\frac{1}{2}}=2\cdot2x \\ =4x \end{gathered}[/tex]We solve this, just dividing 2/0.5=4 and then substituing x.
Now, we substitute x=3, to get the value:
[tex]4x=4(3)=12[/tex]The output value for x=2 is 12.
