The expression of y8x-9 has no solution because without an equality sign it can not be considered to be an equation.
X+9=17;8
If you mean: 3x-9 = 12 then the value of x is 7
the solution is the answer to the equation. A solution is any value that makes the equation true. x + 2 = 10 has exactly one solution ....x=8 x + 2 > 10 has infinitely many solutions....x=9 or 10 or 11 or 12 or 13, etc
If you mean x+4 = 13 then the value of x is 9
The expression of y8x-9 has no solution because without an equality sign it can not be considered to be an equation.
X+9=17;8
Because without an equality sign it can not be considered to be an equation and therefore has no solution.
It is not an equation and no solution is possible.
x - 9 is an expression, neither an equation not an inequality. An expression cannot have a solution.
9 - 4 = 5

Is (7, 9) a solution to the equation y = x?
If you mean: 3x-9 = 12 then the value of x is 7
the solution is the answer to the equation. A solution is any value that makes the equation true. x + 2 = 10 has exactly one solution ....x=8 x + 2 > 10 has infinitely many solutions....x=9 or 10 or 11 or 12 or 13, etc
2 is a solution of the equation, but not if it's an inequality.
Of course, x-1=8 is a solution. Any equation which results with the variable value as 9 is ur answer. For eg: x = 9 / x-9 = 0 1 - x = -8 / x-1 = 8 x-2 = 7 / 2-x = -7 Any, any such equation will be your answer(correct answer). Enjoy
