Answer:
Statements                       Reasons
 1. 2x + 11 = 15                    1. Given 
2. 2x = 4                            2. Subtraction Property of Equality
3. X = 2                              3. Division Property of Equality
Step-by-step explanation:
An equation can be solved and its solution proven using algebraic theorems and properties. To create a proof, form two columns. Label one side Statements and the other Reasons.
Begin your proof listing the any information given to you. List as the reason - Given. 
Then list the next step which here would be to subtract by 11 on both side. The reason is Subtraction Property of Equality. Subtraction is the inverse of addition. Inverse axiom is another acceptable reason.
Then divide both sides by 2. The reason is Division Property of Equality or Inverse axiom once again. See the proof below.

Answer:
this is just math jargon... a conjugate is the same numbers but with an opposite sign.. got it?
Step-by-step explanation:
z1' ( the prime is often used for conjuates it's also used in calculus but later)
