It's a solve for y in one equation problem.

2/3x-5/2y=5

I continue to get y=19x-25

but im sure its wrong, pls help me

Onbe thing to do its multiply through by the LCM of the denomiantors in order to get rid of the fractions.

The LCM of 2 and 3 is 6

\(\displaystyle \L\\6\cdot\frac{2}{3}x-6\cdot\frac{5}{2}y=6\cdot{5}\)

\(\displaystyle \L\\4x-15y=30\)

\(\displaystyle \L\\y=\frac{4}{15}x-2\)

Re: pls help with this problem

2/3x-5/2y=5

Really, you should write these this way:
2x / 3 - 5y / 2 = 5
Then it's much easier to see the denominators: 3 and 2 ; kapish?
