What value of g makes the equation (x 7) (x-4)x 2 gx-28 true?
14
What is an equation that is true for every value?
how about X = X
What does value of variables mean?
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.
What is a linear equation that is not true for even one real number and therefor has no solution?
A linear equation in one variable. Case 1: A conditional equation: True only for a value of the variable. Ex. x + 2 = 3, True only when x is 1. Case 2: Identity Equation: Always true. Ex. x + 2 = x + 2, True for any value of x. Case 3: x + 1 = x + 5, False for any value of x. We call a solution any value of the variable that satisfies the equation, meaning if we replace the variable with that value, the equation becomes a true statement. Example: -2(x -3) = 8 - 2x -2x + 6 = 8 - 2x (add 2x and subtract 6 to both sides) 0 = 2 False. Since this equation, which is equivalent to the original equation, is false, then the original equation is also false. Meaning, there is no real number for x that could satisfy the equation. So there is no solution to the equation.
What does it mean to be a solution of an equation?
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
What is the value for a variable that makes an equation?
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.
What value of y makes this equation true when x equals 3?
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.
What value of x makes 10x equals 350 a true statement?
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.
What value for x makes the following equation TRUE 6x-5 equals 31?
6!
Look at the equation a times x equals 0 What value of x makes this equation true when a is not equal to 0?
In that case, x must be equal to zero. (0)
What value of g makes the equation (x 7) (x-4)x 2 gx-28 true?
14
What is an equation that is true for every value?
how about X = X
What value for x makes the following equation true 3x plus 3 equals 2x plus 6?
3 is the true!
What value of x makes the equation below true. 3(x-6)5x-7?
If you mean: 3(x-6) = 5x-7 then the value of x works out as -5.5

What is the exact answer for 4x-x equals 2x plus x?
6
Equation that is not true for any value?
x - 1 = x + 1
