Question

Part 1:
Solve the following system of equations. Please show your work to receive full credit.
x - y = 16
2x + y = 2

Part 2:
Explain which method you chose to solve the system and why you felt it was the best choice.

Answer 1

y=-10 , x= 6

Answer 2

u can use subsitution method

Answer 3

how did you get that?

Answer 4

@mr.singh Stop giving direct answers,It's against Coc.

Answer 5

x-y=16 .. x=16+y... put in second equation nd solve for y

Answer 6

x - y = 16
2x + y = 2

We add the both equation

remember -y +y will be cancelled...Do it and show me what you get @jaderbrown

Answer 7

I got 6

Answer 8

3x=18
3 3
x=6

Answer 9

x - y = 16
2x + y = 2
========
3x=18
x=18/3
x=6
Correct

Answer 10

now what?

Answer 11

Now take the original 2nd eq and put the value of x

2x + y = 2
So,2(6)+y=2 Right?

Answer 12

yes

Answer 13

Hm so,
2(6)+y=2
12+y=2

Shift the 12 to right side sign changes
So y=2-12
y=-10

Answer 14

thank you!

Answer 15

You're welcome :)
