Answer 3

To solve the equation 14 + 6.2a + 2.4a = 69.9, we need to combine like terms and isolate the variable 'a' on one side of the equation.

Step 1: Combine like terms

We have two terms with 'a': 6.2a and 2.4a. To combine them, we add their coefficients: 6.2a + 2.4a = (6.2 + 2.4)a = 8.6a

Now the equation becomes: 14 + 8.6a = 69.9

Step 2: Isolate the variable 'a'

To isolate 'a', we need to get rid of the constant term on the left side of the equation. We can do this by subtracting 14 from both sides: 14 - 14 + 8.6a = 69.9 - 14 8.6a = 55.9

Step 3: Solve for 'a'

To solve for 'a', we divide both sides of the equation by 8.6: (8.6a) / 8.6 = 55.9 / 8.6 a = 6.5

Therefore, the solution to the equation 14 + 6.2a + 2.4a = 69.9 is a = 6.5.
