Question

-3x -y = -38

-8x+8y = - 16 I got no solution is that correct?

and

y=1/2x -5

y=1/2x +2 i got (20,3) is this correct?

Answer 1

You can check your self by putting

(20,3)=(x,y)

in your equations and check


L.H.S=R.H.S

If

L.H.S=R.H.S then you did it right

If not you are wrong :)

Answer 2

i cant L.H.S=R.H.S for something i got no solution on. can you just tell me weatherr or not im making a mistake please?

Answer 3

There is a solution i guess.

Answer 4

there is a solution,
from 2nd equation, you get -x+y=-2
now add this to 1st equation, and you directly get the value of x.
