1) |7-y| = -2 This equation has no solution because the absolute value of a number is always non-negative, so it cannot be equal to a negative number.
2) |x+3| + 4 = 9 |x+3| = 5 x+3 = 5 or x+3 = -5 x = 2 or x = -8
3) |y-2| + 8 = 5 |y-2| = -3 This equation has no solution because the absolute value of a number is always non-negative, so it cannot be equal to a negative number.
