A submarine began its day 300 feet below sea level and by noon it climbed 200 feet. Around 2 pm the submarine descended 600 feet. What is the depth of the submarine at 2 pm?

500 ft above sea level

i believe the answer is d.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
