Answer 2

I think you should know how to do these by now, you've been giving them all day.

Answer 3

make your life easy and start with

\[5x-3y=13\]
\[-14x+12y=-22\]

Answer 4

multiply the first equation by 4 and add to second, get
\[20x-12y=52\]
\[-14x+12y=-22\]
add to get
\[6x=30\] so
\[x=5\]

Answer 5

then go back and replace x by 5 in either equation. .004*36i choose the first one

\[5\times 5-3y=13\]
\[25-3y=13\]
\[-3y=-12\]
\[y=4\]
