The given equation (2x + 10) = (2y + 30) is not sufficient for determining the value of y. This equation represents a linear relationship between x and y, but without any additional information or constraints, there are infinite possible values for y that satisfy this equation. Therefore, none of the given options (y=15, y=30, y=45, y=90) can be definitively determined as the value of y in the diagram above.
