Identify the type I error and the type II error that corresponds to the given hypothesis. The proportion of people who write with their left hand is equal to 0.16.

To get the variable by itself on one side of the equation and a number on the other side of the equation is our objective in solving the given equation.

We must reverse the operations acting on the variable to separate the variable. By performing the inverse of each operation on both sides of the equation, we can do it. The validity of the equation, or the value of the variable that satisfies it doesn’t change by performing the same operation on both sides of an equation.

11x + 3 = 3

11x = 3 – 3

11x = 0

11(0) = 0

As you can see, the first operation we did on the equation is subtract 3 from 3.

Therefore, the first operation needed to solve the equation 11x + 3 = 3 based on the lesson is subtraction.
