Answer:
x = 9/25, y = 7/25, z = 4/25
Explanation:
step 1: solve for y in first equation to use substitution
y = -2x + 1
step 2: insert into second equation to eliminate y variable and work with two variables
3(-2x+1) + z = 1 (now distribute)
-6x + 3 + z = 1 (bring over the -3)
-6x + z = -2
step 3: now left with -6x + z = -2 and x + 4z = 1, so eliminate z
-6x + z = -2 (multiply by 4)
4(-6x + z = -2)
-24x + 4z = -8
-
x + 4z = 1 (brought down third equation)
-25x = -9
x = 9/25
then just plug in x into the third equation to solve for z, followed by plugging it into the first equation to solve for y. you should end with y = 7/25 and z = 4/25
Because Sandra is reflecting on her career, family and decisions, we can say that this reflection is characteristic of the integrity versus despair developmental crisis.
<h3 /><h3>What is integrity versus despair?</h3>
It corresponds to the eighth stage of the psychosocial development theory developed by Erik Erikson. At this stage the focus is on contemplating your achievements during life, as it occurs around age 65, lasting until death.
In integrity versus despair, the individual will reflect on his experiences and achievements, in order to analyze his life and define whether it was successful or not. When there are negative judgments about their achievements, the individual can develop bitterness and depression.
Therefore, when an individual is able to reflect on his life, career and family in a positive way, he will develop wisdom, which leads to a state of satisfaction, tranquility and joy for the lived experiences.
