Answer:
The solution is 4.
Step-by-step explanation:
Given expression is,
[tex]2.6a+18.4=28.8[/tex]
Subtracting 18.4 on both sides,
[tex]2.6a+18.4-18.4=28.8-18.4[/tex]
[tex]2.6a=10.4[/tex]
Dividing 2.6 on both sides,
[tex]a=\frac{10.4}{2.6}=4[/tex]
Since for a = 4,
[tex]2.6a+18.4=28.8[/tex] is satisfied.
Hence, the solution of the given expression is 4.
