Step-by-step explanation:

10) 52 + 3D = 79

3D = 27

D = $9/DVD

11) a. 72 + 6h = 96

6h = 24

h = 4 hours

b. 7 + 4 = 11 am

12) -200 + 43m = 15

43m = 215

m = 5 minutes

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
