Answer:

Sigmund Freud

Sigmund Freud social scientists believed that people are in constant conflict between their natural impulsive instincts and societal constraints.

What is Sigmund Freud's theory?

Freud could legitimately be referred to as his generation's most important intellectual legislator. His development of psychoanalysis served as a theory of the human psyche, a treatment for its ills, and a lens through which to view culture and society.

The creation of the theory and practice of psychoanalysis is one of Freud's most well-known contributions to psychology.

The importance of the unconscious, early sexual development, repression, dreams, transference, and death and life drives are some of the core principles of psychoanalysis.

Therefore, the Id, ego, and superego, according to Freud, are the three parts of the mind. Interactions and conflicts between these parts lead to personality.

2) How many solutions does the equation 4x + 2(x-5) = 3(2x - 4) have? Write down the final form as well as if it has no solution, exactly one solution, at least two solutions, or infinitely many solutions.

Answers

No solutions ( final form is 0=-2

Answer:

No solution

Explanation:

The first step for this equation is to expand the brackets.

The equation given is: 4x + 2(x-5) = 3(2x - 4)

Once the brackets are expanded, the equation will be: 4x + 2x - 10 = 6x -12

Next up is grouping like terms on each side of the equation. Once all like terms are grouped, the equation will be: 6x - 10 = 6x - 12.  

When you are looking for the "solution" of an equation, you are essentially asking what the value of x is. In order to find the value of x, you must isolate the variable. This means that you have to manipulate the equation in order to have the variable on one side, and the constant on the other side.

6x - 10 = 6x - 12 0x = - 2

Since 6x - 6x leaves 0x, there is no variable. Without a variable pointing towards a constant, there is no solution.
