It is known that the opposite number of X is 3, the absolute value of Y is 4, and the sum of Z and 3 is 0. Find the value of XY + YZ + XZ

It is known that the opposite number of X is 3, the absolute value of Y is 4, and the sum of Z and 3 is 0. Find the value of XY + YZ + XZ

The opposite number of X is 3 ----- > x = - 3
The absolute value of Y is 4: - > y = ± 4
The sum of Z and 3 is 0 ----- > z = - 3
XY + YZ + XZ = y (x + Z) - 3 * (- 3) = - 6y + 9 = 33, or, - 15
