YES X=3

Step-by-step explanation:

10x=3x+21

-3x    -3x

7x=21

. *DIVIDE BY 7 on each side

7     7

X=3

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
