Which sum is equal to 8/12 5/12+3/12
4/6+4/6
2/4+3/4+3/4
2/3+3/4+3/5
me personally think that it is number 3 but i need others input

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
