-4y - x - 3y + 9x

-4y - 3y - x + 9x

-7y + 8x

Well first thing you see -4y and 3y. add +4y to both sides. And then now you have -x - 7y - 9x. Now add 9x to both -9x and -x. So you have 8x - 9y

Shane and Karen want to measure the length of a soccer field. Should they use centimeters or meters to measure it. Explain

Hello!

They should most definitely use meters. Meters are much bigger than centimeters as centimeters are 1/100th of a meter. Meaning, it will take 100 centimeters to get 1 meter. A soccer field is a large surface, and to get a simpler number, you should use meters.

Hope this helps!
