Answer 3

How do you think you start?

Answer 4

-6 + 5x = y

Answer 5

wait I think I might have it, hold on

Answer 6

You have to get the two equations to be divisible by the same number. Since in the second equation, they are all divisible by 3. You would multiply the first equation by 3

Answer 7

y - 15

Answer 8

How did you get that?

Answer 9

6 + 5 x 3 = 15
I honestly don't know how to do this, im trying to study for semester and unit exams.
can you show step by step on how to do it

Answer 10

Sure. Give me one sec

Answer 11

y - 5x = -6 and 3y - 15x = -12 have to both be divisible by the same number. 3y - 15x = -12 are all divisible by 3.

Answer 12

So to get y - 5x = -6 divisible by 3 you have to multiply all of them by 3. y(3) -5x(3) = -6(3)

Answer 13

Do you understand so far?

Answer 14

yes, i'm writing this down

Answer 15

Sorry my internet cut out

Answer 16

You should have gotten 3y - 15x = -18

Answer 17

my computer is acting weird, you can continue

Answer 18

3y - 15x = -18
3y - 15x = -12

Now all you do is subtract

Answer 19

ok

Answer 20

The y's and the x's cancel out. so you are left with 0 = -6. 0 = -6 is never true. Therefore, the answer is no solutions

Answer 21

thanks so much, I hope I do well with these type of questions on the exams

Answer 22

I wish you the best of luck! Is this algebra 1?

Answer 23

yes

Answer 24

Ok. If you need any more help, just let me know. I did really good in algebra 1
