To determine if the equation is true or false, we substitute the given values of x and y into the equation and check if both sides are equal.
Substituting x = 7 and y = 7 into the equation 3x - y = 14, we have:
3(7) - 7 = 14
21 - 7 = 14
14 = 14
Since both sides of the equation are equal, the equation is true.
