Answer

This statement is not true for $x = 12$ and $y = 1$ because both sides of the equation are not true when those values are plugged into the equation.

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: $$12 - 4(1) = 14$$ Multiply first, according to order of operations: $$12 - 4 = 14$$ Simplify: $$8 = 14$$ This statement is not true for $x = 12$ and $y = 1$ because both sides of the equation are not true when those values are plugged into the equation.
