  C.  √15 units

Step-by-step explanation:

The Pythagorean theorem tells you of the relationship between the sides and diagonal of the rectangle:

  8² = 7² +?²

  64 = 49 + ?²

  15 = ?² . . . . . .subtract 49

  ? = √15 . . . . . take square roots

step-by-step explanation:

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
