Question

help?!?!

There are four ways that a system of equations can be solved: graphing, substitution, elimination, or using Cramer’s Rule. Use three or more sentences to describe the process that would be used for solving the system using each of the four methods. You may wish to explain why one method would be better than another for certain problems. Your response should contain a minimum of twelve sentences, three for each method.

Answer 1

...wow...math essays,...

Answer 2

i hate it because i barley know what im doing now... how am i to explain it lol

Answer 3

i hate it because i have difficulties with expressing math in words...im not good with memorizing fancy terms =_=

Answer 4

same here!!!

Answer 5

i can probably give a brief summary of the first three in one sentence...i barely know cramer's rule (i hated matrices)

Answer 6

i dont like em either

Answer 7

graphing - the solution to the equation can be solved by graphing by finding the points of intersections of the graphs

elimination - one would multiply a whole equation by a certain number and then add it to the other equation wherein a variable will be canceled and the other variable/s can be solved from there

substitution - one will substitute an expression for a certain variable to lessen the number of unknown variables to be solved in an equation

Answer 8

you can probably say some shiz to make it longer =)))

Answer 9

again...like i said...im not good with fancy terminologies for math so pardon if im somewhat inaccurate in my descriptions =))

Answer 10

lol thanks!!!!!!! what i was gonna do lol

Answer 11

there are more than 4 ways ....

Answer 12

well i just need the 4

Answer 13

guessing?

Answer 14

prolly could just use the sentences in the material that you study that coincides with this stuff. I dont think they are expecting you to write a doctorial thesis yet :)

Answer 15

prolly lol

Answer 16

yeah they just expect a masteral thesis :p lol

Answer 17

haha

Answer 18

Cramer's rule: write the equations in this form
ax + by = e
cx + dy = f

Compute three determinants

a b
c d

a e
c f

e b
f d

combine them in the proper way

Notice that the first one must be unequal to 0
