Answer 1

A system of equations is shown below.
3x + 8y = 12
2x + 2y = 3
Part A: Create an equivalent system of equations by replacing one equation with the sum of that equation and a multiple of the other. Show the steps to do this. (6 points)
Part B: Show that the equivalent system has the same solution as the original system of equations. (4 points)

Answer 10

ok thanks

Answer 11

:)

Answer 12

So we have to do an elimination method.

Answer 13

i think so

Answer 14

\[\left(\begin{matrix}-2 \\ 3\end{matrix}\right) * \left(\begin{matrix}3x(-2)+8y(-2)\\ \end{matrix}=12\right)\]

Answer 15

Then underneath that equation 2x(3)+2y(3) = 3

Answer 16

Nope, I did not.

Answer 17

Don't tell me you searched it up. If you did then I shouldn't help you.

Answer 18

why -2 and 3

Answer 19

no

Answer 20

i didnt

Answer 21

Be honest.

Answer 22

im serious

Answer 23

Alright, lets start over.

Answer 24

ok

Answer 25

-6x + 14y = -32
-9x + 5y = 16

== -15x + 19y -16

Answer 26

how did u get that

Answer 27

Because we are replacing an equation of the sum of the equation.

Answer 28

Pretty Please

Answer 29

You're making this harder than I thought.

We replace (2) by adding (2) to two time (1):

-6x + 14y = -32 <-- 2 times (1)
-9x + 5y = 16 <-- Add (2)

= -15x + 19y -16

Answer 30

ok you are a big help but just bare with me

Answer 31

(−23)∗(3x(−2)+8y(−2)=12)

Answer 32

why were u doing that

Answer 33

Your answer will be y = 1.5

Answer 34

ok u help me with another in about 10 or 15 min

Answer 35

I'll try but don't forget the medal.

Answer 36

what about part 2

Answer 37

or i mean part b

Answer 38

-6x-16y=-24
6x+6y9

-10y=-15
----------
-10

y=1.5

Answer 39

6x+6y=9**

Answer 40

thats not part b

Answer 41

i got that for part a

Answer 42

i think i just have to check it for part b

Answer 43

Solve (1) and (2) for x,y
Solve (1) and (2) for x,y

Answer 44

@marissalovescats
does x=0
vzfreakz refered me

Answer 45

i just need to know does x=0

Answer 46

x can represent anything number.

Answer 47

but in this situation

Answer 48

does it = 0

Answer 49

Yes x=0

Answer 50

thank you
