Question

solve for a.
9.9 = a - 1.4
a = \boxed{}

Explanation:

Step1: Add 1.4 to both sides

To isolate \( a \), we add 1.4 to both sides of the equation \( 9.9 = a - 1.4 \). This gives \( 9.9 + 1.4 = a - 1.4 + 1.4 \).

Step2: Simplify both sides

Simplifying the left side: \( 9.9 + 1.4 = 11.3 \). Simplifying the right side: \( a - 1.4 + 1.4 = a \). So \( a = 11.3 \).

Answer:

\( 11.3 \)
