You cannot solve z + 7 - 14 since it is not an equation nor an inequality but an expression.
It can be simplified to z - 7 but that is not a solution.
6+z = 3 z = 3-6 z = -3
The equation 7 x + 14 y + 10 z = 98001 has infinite solutions. For any x and y we can have a z which satisfies this equation. For example, if we choose x=1 and y=1 then z=9798 satisfies. To have a specific solution there must be three equations for three unknowns (x,y,z), which can be solved simultaneously.
To solve an equation with three unknowns, x, y and z, you require 3 independent equations.
