Question

Use the substitution method to solve the system of equations. Enter your answer as an ordered pair.

x + 2y = 12
-x = -y - 6

Answer 1

What, another one...?

Answer 2

just tell me in which u r having trouble?

Answer 3

It doesnot makes sense if we go on solving all ur problems coz u will learn nothing

Answer 4

Let us help u

Answer 5

it's not for me. It's for my brother.

Answer 6

Ahh I can see that, well then
x=y+6
Now substitute into 1
y+6+2y=12
3y=6
y=2
x=2+6=8

Answer 7

(y+6)+2y = 12
y+6+2y = 12
3y = 12-6
y = 6/3
y = 2
substitute y in equation
x+2(2) = 12
x+4 = 12
x = 12-4
x = 8
so, x=8,y=2

Answer 8

lol ... tell your brother to do his own work ;)

Answer 9

it will be like this we will multiply both side of this : -x=-y+16 into minus so we will get x=y+6
Now it is time to sustitute in the question:
x+2(2)=12
x+4=12
x=8
then we will get x=8,y=2

Answer 10

id just use it as is:

x + 2y = 12
-x = -y - 6
---------------
2y = -y +6 ; +y

3y = 6 ; /3

y = 2 ; use that to determine the value of x
