Hi!
This is NOT an equivalent expression.
Since y values and x values can not be combined, there would be no way to combine the equation on either sides.
TO SOLVE:
Take off the parentheses
9x+2y=4x + y (or 1y)
These two are not equal!!

Answer: 13x+3y

Explanation: because u can add both the x and y variables since they're both the same for each side.
