y = -2.5 is a equation. And solution to the equation is finding the value of the variable. If we see the equation y is already equal to -2.5 which is the solution to the equation.
If: 5x+2y = 9 Then: y = -2.5x+4.5 in slope intercept form
Root means solution in this context.
A solution to an question makes the equation true. For example a solution to the equation 3x = x + 6 is x = 3, since 3(3) = 3+6.
On the list that accompanies the question, there is no equation with that solution.
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?
a solution to an equation is the answer
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.
