1 answer

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: \[ c = 4.2 \]
