Given the equation:

[tex]y-7.8=5.5[/tex]

You need to solve for "y" in order to find its value. In this case, you need to apply the Addition Property of Equality, which states that, if:

[tex]a=b[/tex]

Then:

[tex]a+c=b+c[/tex]

Therefore, you need to add 7.8 to both sides of the equation in order to solve for "y":

[tex]\begin{gathered} y-7.8+(7.8)=5.5+(7.8) \\ y=13.3 \end{gathered}[/tex]

Hence, the answer is:

[tex]y=13.3[/tex]
