7x + 9 = 6x + 17 7x - 6x = 17 -9 x = 8

In algebra, variables are represented by letters such as x. A variable could be any number. That number is the "value" of the variable. In an expression, you can choose a number to put in for x, and simplify to get a number which is the value of the expression. In an equation, you can solve for the value of x, which will be the value of x which makes the equation true.
how about X = X
Unfortunately the sentence is missing to be able to get the value of x.

3x + 8 = 4x + 23x - 4x = 2 - 8-x = -6x = 6
It depends on the sentence.
It's the value that when substituted in for the variable, makes the equation true. Ex: x + 1 = 3 The value 2, when substituted for the variable x, makes the equation true.
solution
x - 2 = 4x + 46-2 = 3x + 46-48 = 3xx = -48/3 or -16
an open sentence can be either true or false, depending on what values are substituted for the variables. A SOLUTION of an open sentence with on variable is a value that makes the sentence true. The solution of the equation x+3=5 is 2. One solution of the inequality x-1>4 is 6, and there are many more solutions. hope this helps
Value is the number you're looking for that will make a math sentence true. Like x=2+5 x=7
7x + 9 = 6x + 17 7x - 6x = 17 -9 x = 8
Any value of x that is more than 4, for example 4.000000000000001
so you are asking: When does 1/x = x% become true? It doesn't make sense. 1/x = x is true when x = 1 But it is never true with the percentage sign at the end.
