We need to solve the following expression:
[tex]w+2\frac{1}{2}=3\frac{1}{2}[/tex]To do that we have to isolate the w variable on the left side of the equal sign, this is done by changing the signal of the constant number as shown below:
[tex]w=3\frac{1}{2}-2\frac{1}{2}[/tex]We can now subtract the two mixed fractions to determine the value of w.
[tex]\begin{gathered} w=3\text{ + }\frac{1}{2}-(2+\frac{1}{2}) \\ w=3-2+\frac{1}{2}-\frac{1}{2}=1 \end{gathered}[/tex]The value of w is 1.
