Question

medal to any one who helps and fan

Answer 1

A system of equations is shown below:

-3x + 7y = -16
-9x + 5y = 16

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

I dont know what it is asking

Answer 11

if you help with part a I dont think ill need any more help that is where I am stuck

Answer 12

Part A means to isolate one variable (x or y) by solving the equation. Then using (x= oe y=) plug whatever you get into the other equation

Answer 13

it is saying how is it the same

Answer 14

do you know the substitution method?

Answer 15

no I dont

Answer 16

and @kamarigood123 I dont know what is supposed to be the same

Answer 17

basically, try to solve for x by moving everything besides x to the right. so you get x= (##)

Answer 18

can you do that?

Answer 19

chooose one of the equations and solve for x

Answer 20

yes but which equation should I do

Answer 21

you can pick which ever, either one will solve the problem.

Answer 22

ok so im doing the top and I got
x=-16 -7y+3 is that right

Answer 23

good for you

Answer 24

so thats right?

Answer 25

yes

Answer 26

ok then what do I do

Answer 27

so put in and where done ok
