Solve the equation show your work 4/a=5/100

cross multiply the two numbers.

4x100=400

5xa=5a

now set them equal to each other

400=5a

Divide 5a on both sides you get 80.

a=80

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
