Answer 1

Help Help!!

Answer 2

have you ever tried to solve it yourself? Where do you have problem?

Answer 3

Is the second equation copied correctly?

Answer 4

system is:

ok

Answer 6

i did not mean to put the equal sign in front of second equation

Answer 7

this one i need some help with and yes of coarse i tried on my own. if you do not mind i would greatly appreciate help with this one. Thank you

Answer 8

x+8y=14
3x+4y=0
---
x=14-8y
*
---
*
3(14-8y)+4y=0
---
*
42-24y+4y=0
---
*
-20y=-42
y=2,1
---
x+8(2,1)=14
x+16,8=14
x=-2,8

x=-2,8
y=2,1

Answer 9

solve it the same way we helped you in previous questions...
from first equation, you know that x = ######
so you can substitute into second equation
3*(#####) +4y=0
now you know what is y and then you plug y value back to first equation to get what is x
