We want to answer the equation 10x = 350 This can be done by dividing both sides by 10. That makes the equation x = 35. Thus the value of x that makes 10x=350 is 35.

In that case, x must be equal to zero. (0)

If you mean: 3(x-6) = 5x-7 then the value of x works out as -5.5

Without an equality sign and not knowing the plus or minus values the given information can't be considered to be an equation.

Identities are "equations" that are always true. For example, the equation sin(x) = cos(x) is true for x = pi/4 + kpi radians where k is any integer [ = 45 + 180k degrees], but for any other value of x the equation is not true. By contrast, the equation sin2(x) + cos2(x) = 1 is true whatever the value of x. This is an identity.

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

In the equation x = 3, if x = 3, the equation is true, if x has any other value, it is not. The value of any other variable, such as y, is irrelevant. I would say that the answer is 0 because otherwise y is part of the equation which clearly it isnt.

how about X = X

3 is the true!

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.
