question 1-2
solve the equation
3.4a + 6.1 = 12.9
a =

Explanation:

Step1: Subtract 6.1 from both sides

To isolate the term with \( a \), we subtract 6.1 from both sides of the equation \( 3.4a + 6.1 = 12.9 \). This gives us:
\( 3.4a + 6.1 - 6.1 = 12.9 - 6.1 \)
Simplifying both sides, we get:
\( 3.4a = 6.8 \)

Step2: Divide both sides by 3.4

To solve for \( a \), we divide both sides of the equation \( 3.4a = 6.8 \) by 3.4:
\( a = \frac{6.8}{3.4} \)
Calculating the right - hand side, we find that \( a = 2 \).

Answer:

\( a = 2 \)
