Suppose eight out of every 20 students are absent from school less than five days a year predict how many students will be absent from school lesson five days a year out of 40,000 students

8/20*40,000

2/5*40,000

80,000/5

160,000/10

16,000 students

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
