Answer

The statement is true for $x = 2$ and $y = -3$.

Work Step by Step

To determine if the statement is true for a certain value for $x$ and $y$, we need to plug those values into the equation to see if both sides of the equation are equal: $$2 - 4(-3) = 14$$ Multiply first: $$2 -(-12) = 14$$ If we subtract a negative number, it means the same as adding a positive number: $$2 + 12 = 14$$ Add the terms together: $$14 = 14$$ The statement is true for $x = 2$ and $y = -3$.
