Question

2x+y=-8 x-2y=-6 solve the system of linear equations

Answer 1

x=-8-y/2 from eq1
put value of x in eq2
you'll get x ..
then put actual value of x in any of the 2 eq you'll get y

Answer 2

or second way is to solve them by matrices
using echelon form .

Answer 3

this is wut i got
y=45 and x=-22/5

Answer 4

answers are wrong they ain't satisfying the eq

Answer 5

2x+y=-8.........(1)
x-2y=-6 .........(2)

multiply equation 1 by 2

4x+2y=-16
x-2y =-6

add both eqns

5x=-10
x=-2

substitute and find y

Answer 6

oops mistake adding both equans

5x=-22

Answer 7

so u are right @Astemmene

Answer 8

lalaly solutions aint satisfying the eqs

Answer 9

yeah mee!!! :D

Answer 10

let me check

Answer 11

the y should = 4/5 not 45

Answer 12

woops i wrote it out wrong but thats wut i ment :P

Answer 13

lol its ok xD

Answer 14

i m getting x= -14/3
y = 4/3
