Question

Which equation shows the substitution method being used to solve the system of linear equations?

x + y = 6
x = y + 2

A.
x = (x – 6) + 2

B.
x + y = y + 2

C.
x + (y + 2) = 6

D.

Answer 2

Why do you think that? We know the value of x, so there should be no x's once we substitute.

Answer 3

Oh so C

Answer 4

There is an x in C :)

Answer 5

it just says Which equation shows the substitution method being used to solve the system of linear equations?... not solve for it??

Answer 6

But yes, you are correct.

Answer 7

:))) Thanx @sleepyjess

Answer 8

D is correct.
for anyone curious...
2y+2=6
2y=4
y =2

x+2=6
x=4

Answer 9

I'll tell you guys if your right

Answer 10

But i 'm gonna choose C

Answer 11

ugh I'm getting confused now, @UsukiDoll is correct

Answer 12

Oh.

Answer 13

That was my answer at first tho -.-

Answer 14

seeeeee.............. re read the question
Which equation shows the substitution method being used to solve the system of linear equations?
x + y = 6

x = y + 2

If we let x = y+2, we have

(y+2)+y=6

Answer 15

Thank you @UsukiDoll

Answer 16

I miss doing easy stuff... I'm screwed with hard math D: not fun depending on the subject. Euclidean Geometry is fun.. Mathematical Bio... is a pain-o

Answer 17

same, I'm in pre-calc right now, and I hate it
