Answer 2

hi can u help me

Answer 3

@surdawi

Answer 4

hi

Answer 5

Yeah i am really lost sorry all!

Answer 6

use the first equation to isolate y on the left hand side. Once you have that you can plug that value of y into the second function and solve it for x.

Once you have the value of x you can go back to the first fuction to compute y

Answer 7

Although i still dont understand i will try my hardest

Answer 8

I think it is all the plus and minus signs plus the variables that are getting me the most

Answer 9

a) 2x-y =6
b) x+2y=3

from a)
2x = 6 +y
2x -6 = y

now we can use that in the b)
x + 2 * ( y ) = 3
x + 2 * ( 2x - 6 ) = 3
... continute to solve for x

once you know the value of x you can substitute it back into
2x -6 = y

and this will give you the value of y

Answer 10

So x =3 then
I am sorry I am so confused and wasting your time thank you for your help
