Ms. Rossi was the principal of a public school in the United States in 2014. There were 200 students at the school. In round numbers, if the school's rates of poverty were representative of the United States, approximately how many of its students were living in poverty

the answer would be done like this

Step-by-step explanation:

you have to get y by itself so you would need to move the x to the right of the equal sign

once you move anything to the opposite side it switches, so positive becomes negative vice versa

-3y=-x+18

you need to make sure you have positive 1 y so you would divide y by -3 to make it 1

everything else is multiplied by -3 as well

so the answer would be y=⅓x-6
