Answer:
a = 6
Explanation:
Given the expression;
[tex]\frac{a}{2}-2.2\text{ = 0.8}[/tex]Add 2.2 to both sides
[tex]\begin{gathered} \frac{a}{2}-2.2+2.2\text{ = 0.8 + 2.2} \\ \frac{a}{2}\text{ = 3.0} \end{gathered}[/tex]Multiply both sides by 2;
[tex]\begin{gathered} \frac{a}{2}\cdot2=3.0\cdot2 \\ a\text{ = }6.0 \end{gathered}[/tex]Hence the value of a is 6
