Answer 1

you can do elimination method because that that would be easy

Answer 2

I forgot how to do the elimination @Nnesha you got this one

Answer 3

so in order to do elimination you have to eliminate 1 variable to solve the equations!

Answer 4

can you do elimination even though it says substitution?

Answer 5

where it says substitution ??

Answer 6

it says solve using substitution @Nnesha

Answer 7

okay then we can do substitution method
you can do any method u gonna get same answer
so for substitution you have to solve one of equation for one variable

Answer 8

so i guess you should solve 2nd equation for y
that gonna be easy
so 2x + - y = 6 solve this for y

Answer 9

-y = 4?

Answer 10

you can't combine 6 and 2x bec 6 doesn't have any x

Answer 11

so live that as it is
-y = -2x + 6
now divide by negative sign

Answer 12

so I would rewrite it as y = 2x + 6?

Answer 13

2x is positive on left side so you have to subtract 2x both side

Answer 14

-3

Answer 15

now divide by negative one
