What do you know about it? Answer this for me: \[x+2y=12\]\[a)(1,6)\]\[b)(5,2)\]\[c)(7,2)\]

OpenStudy (anonymous):

That idek

OpenStudy (anonymous):

its been awhile since ive done this

OpenStudy (dangerousjesse):

Okay, that's fine :) \[x+2y=12\]To substitute, replace x with the first number in the coordinate and y with the second. Let's go with option one first, (1,6)

OpenStudy (dangerousjesse):

Substitute x with 1 and y with 6. Does that equal 12?

OpenStudy (anonymous):

NO

OpenStudy (dangerousjesse):

Do the same with option two.

OpenStudy (anonymous):

Ok

OpenStudy (anonymous):

C.

OpenStudy (dangerousjesse):

\[7+(2\times2)=12\]Yup. Do you understand how to substitute now?

OpenStudy (anonymous):
