Y - (-9) = –16
linear equations

y=-25

Step-by-step explanation:

step 1: simplify both sides of the equation

y+9=−16

step 2: subract 9 from both sides

y+9−9=−16−9

y=−25

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

it would open into a square depending on the type of envelope i’m not sure about the second part
