Answer 2

Expression Evaluation

To find the value of the expression (х + 4) + (у - 2) - (z + x), we need to substitute the given values of x, y, and z into the expression.

Given: - x = -4 - y = 20 - z = 2

Substituting these values into the expression, we get: (-4 + 4) + (20 - 2) - (2 + (-4))

Simplifying the expression step by step: 0 + 18 - (-2) 0 + 18 + 2 20

Therefore, the value of the expression (х + 4) + (у - 2) - (z + x), when x = -4, y = 20, and z = 2, is 20.
