WHO EVER ANSWERS IT RIGHT I WILL MARK BRANLEIST

1) 6.8127*10^16

2) 2.9544*10^24 in scientific notation.

Step-by-step explanation:

for problem 2, I added the four masses and then divided by 4 to get the answer 2.9544*10^24 or 2.9544e24.

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
