]i have a cpl of these that will be on a test. and would appreciate it if someone can show me a really quick and easy way to solving this? also, how to solve this equation?y=2/3=5/12 and x+1/9=7/9? also, 2/3x=7=ty

Hi;

This is not in the right form.

y=2/3=5/12

For the next one:

Subtract 1 / 9 from both sides.

For the last

2/3x=7=ty

which variable do you want to solve for?

this is the problem as written on sample test ---Y-2/3=5/12==solve equation and simplify! THE NEXT ONE IS 2/3x=7 and another x+1/9= -7/9--- i am copying all these problems from a sample math test---and that is how they are written! "-D

Hi;

You should notice that in post#1 you have written

y=2/3=5/12

and in post #3 you have

Y-2/3=5/12

these are not the same, that is why I asked.

This one is in a form we can solve for

Add 2 / 3 to both sides.

Do you follow this so far? Are you familiar with how to add to fractions? Or do you need some help with that?
