Question

Solving linear systems by substitution.
How do I do it?

Examples: x=8
-7=4

Answer 1

that is not a system of equations..

Answer 2

do you have a specific problem to work on, or should I make some examples?

Answer 3

out of those two? those two mean nothing to me-:( sorry

Answer 4

I will post some examples.

Answer 5

sure

Answer 6

(one at a time, pliz)

Answer 7

It says Suppose you try to solve systems of liner equations using substitution and get results below. How many solutions does each system have?

1. x=8

Answer 8

I do not see any system of equations.

Answer 9

I'm assuming you are copying and pasting, and it isn't showing up

Answer 10

I don't understand what you are asking, a system of linear equations is something like:
\(\large\color{blue}{ 2x+ 3y=4 }\)
\(\large\color{blue}{ y=-5x-3 }\)

Answer 11

I can't really help you much again, if I can't fully see the problem you are trying to solve.

Answer 12

you can type your equations, can't yu>?

Answer 13

That is what it shows that I need to solve.

It says.

Suppose you try to solve systems of liner equations using substitution and get results below. How many solutions does each system have?

Then the first example is \[x=8\]

Answer 14

this is wrong though

Answer 15

try takinga screen shot of the problem instead @BraydonG

Answer 16

Its the example question

Answer 17

x=8, is a vertical line (with none-existing slope, and all that...)
and NOT a SYSTEM of LINEAR equationS

Answer 18

hold on guys I am uploading a PIC

Answer 19

good;0

Answer 20

question, is an undefined slope the same as none-existing..? or is a zero slope a non-existing slope... @SolomonZelman

Answer 21

A slope is a number of y-units up per 1 x-unit to the right.
A vertical line never goes to the right, so I am more thinking that not that it is undefined, but it is unapplicable to a vertical line. it doesn't exist in a vertical line.

Answer 22

Technically, it is all same though.

Answer 23

Ah, I see. :) haha, cause y=2, for example, has a zero slope, so I was just wondering the specifics

Answer 24

very nice

Answer 25

Installing Drivers.

Answer 26

take your time, no rush... even if I won't be online, someone else can help

Answer 27

can you draw it, using the button "draw" below?

Answer 28

If you need a better one please ask. @SolomonZelman

Answer 29

You still there @SolomonZelman ?

Answer 30

Well Now that i know there must be One Solution, No Solutions, or Infinitely many solutions.
