Sending multiple sets of information on SoftwareSerial

Using Arduino Project Guidance
3

This is the code for the transmitter (just for testing the code)

#include <SoftwareSerial.h>

SoftwareSerial hc(10, 11); // HC-12 TX Pin, HC-12 RX Pin

double first;
double second;

void setup() {
  // put your setup code here, to run once:
  hc.begin(9600);
}

void loop() {
  // put your main code here, to run repeatedly:
  hc.write(first, second); //the  compiler shows "no matching function for call to 'SoftwareSerial::write(double&, double&)'"

  delay(5);
}

And this is the code for the receiver (just for testing the code)

#include <SoftwareSerial.h>

SoftwareSerial hc(10, 11); // HC-12 TX Pin, HC-12 RX Pin

double first;
double second;

void setup() {
  // put your setup code here, to run once:
  hc.begin(9600);
  Serial.begin(9600);
}

void loop() {
  // put your main code here, to run repeatedly:
  if(hc.available()){
    hc.read(first, second);  //the  compiler shows no matching function for call to 'SoftwareSerial::read(double&, double&)'

    Serial.write(first);
    Serial.write("is the first value and");
    Serial.write(second);
    Serial.println("is the second value");
    delay(250);
  }
}

I also tried in the receiver code,
hc.read() = first, second;
but the compiler shows "lvalue required as left operand of assignment"
