Answer 3

ouu

Answer 4

We want to get rid of a variable here too, since 6 and 4 are easier numbers to find common factors from, lets get rid of y

Answer 5

12?

Answer 6

Right, so what times 6 gives you 12?
What times 4 gives you 12?

Answer 7

2 an 3

Answer 8

So you would multiply each equation respectively
\(\color{red}{-2(}13x-6y=2\color{red}{)}\\
\color{red}{-3(}3x-4y=-10\color{red}{)}\)

Answer 9

-26x-12y=-4
-9x-12y=30

Answer 10

+12y*

Answer 11

miss pushed

Answer 12

Ah that was my mistake only one of them should be multiplied by a negative

Answer 13

This \(-26x-12y=-4\\
-9x+12y=30\)
Or this

\(-26x+12y=-4\\
-9x-12y=30\)

Answer 14

-35x=26

Answer 15

No, I am just telling you to chose one

Answer 16

segundo

Answer 17

Ah crap, I made another mistake

Answer 18

im also practicing my spanish lel

Answer 19

Lets do this one (this is what I was doing for the second one)
\(\color{red}{-2(}13x-6y=2\color{red}{)}\\
\color{red}{3(}3x-4y=-10\color{red}{)}\)

Answer 20

-26x+12y=-4
9x-12y=-30

Answer 21

-17x=-30

Answer 22

that isnt right o~O

Answer 23

Add -30 and -4

Answer 24

x=2

Answer 25

Now substitute that into one of the equations

Answer 26

13x-12y=2

Answer 27

\(13x-6y=2\) Not the right equation lol

Answer 28

"one of the equations"

Answer 29

o wait

Answer 30

From the problem

Answer 31

13x-24y=2

Answer 32

now im confused XD

Answer 33

\(13x-6y=2\\
3x-4y=-10\)

Answer 34

3x-8y=-10

Answer 35

Where did you get the 8 from?

Answer 36

*facedesk*

Answer 37

26x-6y=2

Answer 38

Just chose one of the equations I just wrote lol

Answer 39

Answer 40

seufhfbefjiokeesfefaf e.e the second one

Answer 41

\(3x-4y=-10~~~~~~~~~~~x=2\)
Substitute
\(3(2)-4y=-10\)
Now solve that

Answer 42

6-4y=-10
-4y=-16
y=4

Answer 43

So...
\((2,4)\)

Answer 44
