It seems you are presenting a series of equations and their verbal interpretations. Here is a clarification of the equations:
-
\( y + 9 = x + 10 \) translates to "y plus 9 is equal to x plus 10". (This is correct.)
-
\( y = \frac{10}{9} x \) translates to "y is equal to 10 ninths x". (This is correct.)
-
\( y + 10 = x + 9 \) translates to "y plus 10 is equal to x plus 9". (This is correct.)
-
\( y = \frac{9}{10} x \) translates to "y is equal to 9 tenths x". (This is correct.)
