Short Answer

Expert verified

The solution of the given equation is a=9.

Step by step solution

01

Step 1. Write the given equation.

The given equation is “0.6a+9=14.4”.

02

Step 2. Solve the given equation.

Solving,

0.6a+9=14.4 (Given equation)

0.6a+9−9=14.4−9 (Subtract 9 from both sides)

0.6a=5.4 (Simplify)

0.6a0.6=5.40.6 (Divide both sides by 0.6)

a=9 (Simplify)

So, a=9is the solution of the given equation.

03

Step 3. Check the obtained solution.

Put a=9in the given equation 0.6a+9=14.4to get,

0.69+9=14.45.4+9=14.414.4=14.4

Since the value obtained on the left-hand side and right-hand side are equal, the obtained value is indeed a solution of the given equation.
