Multiple Choice

A technical analyst is solving the equation 7.8x + 4 = 5.4x - 8 to determine signal variance in a communication model. After the first step of collecting variable terms, the analyst arrives at the simplified state: 2.4x + 4 = -8. According to the standard solving procedure, what is the resulting constant value on the right side of the equation after the analyst subtracts 4 from both sides to isolate the variable term?
