Respuesta :

Four! Answer has to be 20 characters long

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.
