If you mean z-9=3, then z=12. That means you can make any algebraic expression that makes sense. e.g. z+1=13.
It is not an equation and no solution is possible.
That's an invalid equation.
Without an equality sign the given expression can't be considered to be an equation.
3x - 2 = 9 3x = 9 + 2 = 11 x = 11/3
To solve the equation (10x - 9 = 21), first add 9 to both sides to get (10x = 30). Then, divide both sides by 10 to find (x = 3). Thus, the solution to the equation is (x = 3).
It is not an equation and no solution is possible.
That's an invalid equation.
2 is a solution of the equation, but not if it's an inequality.
Without an equality sign the given expression can't be considered to be an equation.

3x - 2 = 9 3x = 9 + 2 = 11 x = 11/3
The expression of y8x-9 has no solution because without an equality sign it can not be considered to be an equation.
3X = 9 divide both sides integers by 3 (3/3)X = 9/3 X = 3 -------------check in original equation, put 3 in for X 3(3) = 9 9 = 9 ----------checks
X+9=17;8

x - 9 is an expression, neither an equation not an inequality. An expression cannot have a solution.
