Ok heres the question. (5/3x)-(5/2)=-(4/9)
Here is how i understand how to figure it out. It asks me to solve for x, write answer as fraction and in simpilest form.
6(5/3x-5/2)=6(-4/9)
then i got
6(5/3x)-6(-5/2)=6(-4)
30x-30=-24
30x-30+30=-24
30x=-24
Then i divided both sides by 30 and got -(4/5) but that wasnt right.
heres another question that i asked my professor about. same type.
(9/8x)+(3/4)=(7/2)
8((9/8x)+(3/4))=8(7/2)
8(9/8x)+8(3/4)=8(7/2)
9x+2(3)=4(7) simplifies to 9x+6=28
then he got 9x+6-6=28-6
9x=22, then he divided both sides by 9 and got (22/9).
Im really confused. cause i did a couple and emailed him all my work and answers and they were wrong. So i dont know what to do anymore.
