Question

Solve the following system of equations.
5x-7y=17
−7x+9y=−19


x=___
y=___

Answer 1

we can do it, it is going to take a couple steps and the answer is messy
if you want the y terms to drop out, multiply the first equation all the way across by \(9\) and the second all they way across by \(7\)
let me know what you get

Answer 2

what?

Answer 3

multiply each term in \[2x-7y=17\] by \(9\)

Answer 4

oops i meant in \[5x-7y=17\]

Answer 5

18x-63y=153

Answer 6

45x

Answer 7

right

Answer 8

-49+81=-133

Answer 9

\[45x-63y=153\]

Answer 10

Answer 11

i did

Answer 12

-49+81=-133

Answer 13

Answer 16

i know

Answer 17

u should get \[-49x+63y=-133\]

Answer 18

correct

Answer 19

you have now \[45x-63y=153\\
-49x+63y=-133\] now add in a column and the y terms will go bye bye

Answer 20

what lol

Answer 21

add the first line and the second line

Answer 22

what is \(45x-49x\)?
