Question

Y-3 over Y+3=2/5

Answer 1

what is y?

Answer 2

\[\frac{y-3}{y+3}=\frac{2}{5}\iff 5(y-3)=2(y+3)\] solve for y

Answer 3

I got an answer of 7. Is that correct?

Answer 4

(y-3)/(y+3) = 2/5
Cross multiply
2(y+3) = 5(y-3)
2y +6 = 5y -15
15+6 = 5y-2y
21 = 3y
21/3 = y
7 = y
Yes your answer is correct
