15(25-5a)=4-a
375-75a=4-a
Add 75a to both sides
375= 4+74a
Subtract 4 from both sides
371=74a
Divide both by 74
5.01=a

Answer:

The value of the equation for a is 371/74 or 5.0135.

Explanation:

Consider the provided equation.


15(25-5a)=4-a

We need to solve the provided equation for a.

Open the parentheses.


375-75a=4-a

Add a to both side.


375-75a+a=4-a+a


375-74a=4

Subtract 375 from both the sides.


375-375-74a=4-375


-74a=-371

Divide both the sides by -74.


a=(371)/(74)

Hence, the value of the equation for a is 371/74 or 5.0135.
