To solve the equation \( c + 4.2 = 8.4 \), you need to isolate the variable \( c \). Here are the steps to solve it:
1. Subtract \( 4.2 \) from both sides of the equation:
\[
c + 4.2 - 4.2 = 8.4 - 4.2
\]
This simplifies to:
\[
c = 8.4 - 4.2
\]
2. Calculate \( 8.4 - 4.2 \):
\[
8.4 - 4.2 = 4.2
\]
So, the solution is:
\[
c = 4.2
\]
1. Subtract \( 4.2 \) from both sides of the equation:
\[
c + 4.2 - 4.2 = 8.4 - 4.2
\]
This simplifies to:
\[
c = 8.4 - 4.2
\]
2. Calculate \( 8.4 - 4.2 \):
\[
8.4 - 4.2 = 4.2
\]
So, the solution is:
\[
c = 4.2
\]
