The equation (4x - 5y + 5z = -84) is a linear equation in three variables (x, y, and z). It represents a plane in three-dimensional space. To analyze it, you can express one variable in terms of the others, such as (z = \frac{-84 - 4x + 5y}{5}), or find specific solutions by assigning values to two of the variables.
567 + 193 + 84 = 844

17+67= 84
42 + 42 = 84
3x + 4x = 847x = 84divide both sides by 7x = 12
79 + k = 84 84 - 79 = k k = 5

7x + 8 = 84 7x = 84 - 8 x = 76/7 x = 10.8571
