9) In a study of 200 students under 25 years old, 20% have not yet learned
to drive. How many students cannot
drive?

40 students cannot drive

Step-by-step explanation:

200 divided by 10 = 20

20 times 2 = 40

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

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
