z + 8 - 2 is an expression, not an equation. An expression cannot be solved. At best, you can simplify it to z + 6.
There is no equation (or inequality) to solve. 15yz is an expression and an expression cannot be solved.
The question consists of an algebraic expression. There is no equation nor inequality which may be solved.
Without an equality sign the given expression is not an equation and so therefore a solution is not possible.

Because it is "solved for x", x will be by itself on one side of the equation. On the other side will be what x equals.
An equation or an inequality can be solved but an expression cannot be solved.
It depends on the equation that is being solved.
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.
That is called "solving for a variable". If there is only one variable in the equation, then it is a "solution". For example, 3x + 4y = 13 can be solved for x as 3x = -4y + 13 x = -(4/3)y + 13/3 This is solved for x. Another equation with only one variable: 5z - 6 = 4 5z = 10 z = 2 This is a solution.
A quadratic equation normally has 2 solutions and can be solved by using the quadratic equation formula.
