Q. Evaluate the expression for g=−1g = -1.\newlineWrite your answer as a decimal or whole number.\newline7+15.4g=7 + 15.4g = _____
  1. Substitute g=−1g = -1: Substitute g=−1g = -1 into the expression 7+15.4g7 + 15.4g.\newlineExpression after substitution: 7+15.4(−1)7 + 15.4(-1)
  2. Multiply by −1-1: Multiply 15.415.4 by −1-1.15.4×−1=−15.415.4 \times -1 = -15.4
  3. Add to 77: Add the result from Step 22 to 77.\newline7+(−15.4)=7−15.47 + (-15.4) = 7 - 15.4
  4. Calculate the sum: Calculate the sum. 7−15.4=−8.47 - 15.4 = -8.4
