1.02 X 10^2
8.54 X 10^-3
6.83 x 10^-4
9.12 X 10^-6

Step-by-step explanation:

1.02 X 10^2=102

8.54 X 10^-3=00.854

6.83 x 10^-4=0.000683

9.12 X 10^-6=00000.0912

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
