Question

solving systems of equations by elimination
-x + 9y = -5
x - 5y = 1

Answer 1

Add the second equation to the first equation to get 4y=-4

Answer 2

Then, divide -4 by 4 to get y=-1. Plug in -1 for y into either equation and solve for x.

Answer 3

x-5y=1
x-5(-1)=1
x+5=1
x=-4

Answer 4

Then plug x and y back into either equation to check your answer.

Answer 5

do i add or subtract them

Answer 6

add :)

Answer 7

ty :D

Answer 8

No problem!

Answer 9

-4+-1

Answer 10

with will be -5

Answer 11

whitch*

Answer 12

Wait..

Answer 13

-(-4) + 9(-1) = -5
(-4) - 5(-1) = 1

Plug them into these equations to check

Answer 14

omg im new too this subject lol like ugh

Answer 15

haha don't worry about it, you'll get the hang of it!

Answer 16

just know...the solution would be (-4, -1)

Answer 17

for the answer right ill let you kno if i need help on the next one

Answer 18

Okay

Answer 19

Did you understand how I got that?

Answer 20

thanks again

Answer 21

No problem!

Answer 22

y = 2/3x-1
y=3

Answer 23

y = 2/3x-1
y=3

Answer 24

are those the two equations given?

Answer 25

yes

Answer 26

okay, so 3=2/3x-1

y is given so we have (_, 3) so far.

Answer 27

ok

Answer 28

3+1=2/3x
4=2/3x
4*3/2=x
x=6

so (6, 3) :)

Answer 29

THANKS!

Answer 30

No problem!

Answer 31

8 more to go idk if you going to help me with all this lmao
