Q. Evaluate the expression for y=3.1y = 3.1 and z=2z = 2.\newlineWrite your answer as a decimal or whole number.\newlineyz−z=yz - z = _____
  1. Substitute values into expression: Substitute the given values for yy and zz into the expression yz−zyz - z.\newlineExpression: (3.1×2)−2(3.1 \times 2) - 2
  2. Calculate product of y and z: First, calculate the product of yy and zz.\newlineMultiply 3.13.1 by 22.\newline3.1×2=6.23.1 \times 2 = 6.2
  3. Subtract zz from product: Now, subtract zz from the product of yy and zz.\newlineSubtract 22 from 6.26.2.\newline6.2−2=4.26.2 - 2 = 4.2
