ANSWER

[tex]a=30.2[/tex]

EXPLANATION

We want to find a from the equation:

[tex]7=\frac{a-9.2}{3}[/tex]

The first step is to multiply both sides of the equation by 3:

[tex]\begin{gathered} 7\cdot3=a-9.2 \\ \Rightarrow21=a-9.2 \end{gathered}[/tex]

The next step is to add 9.2 to both sides of the equation:

[tex]\begin{gathered} 21+9.2=a-9.2+9.2 \\ \Rightarrow a=30.2 \end{gathered}[/tex]

That is the answer.
