Question

step by step help 2x+y=-6

Answer 1

no

Answer 2

where did 7 come from

Answer 3

he was wrong what are you trying to find?

Answer 4

it is system of equations:elimination method

Answer 5

ok what is the other equation

Answer 6

3x+y= -10

Answer 7

2x+y=-6
3x+y=-10
ok, then substract the to eq from each other
2x+y=-6
-(3x+y=-10)
so
-3x-y=10
so
2x+y=-6
-3x-y=10

-x=4
divide by -1 both side
so x=-4
now sub in on of the eq
2(-4)+y=-6
-8+y=-6
+8 to both sides so
y=2

Answer 8

do you follow this?

Answer 9

just a sec

Answer 10

yes thank you

Answer 11

how do you gt the solution suppose to be 2 answers

Answer 12

it is x=-4 and y= 2

Answer 13

what site can i use if i need more help?

Answer 14

this one or ask.com

Answer 15

or me :-)

Answer 16

is there a short cut of doing these equations?

Answer 17

no just look at the two variables and see which is easiest to elimate. some times you have to multiply both equations by numbers to elimate one of the variables, sorry.
