If it's a simultaneous equation in x and y variables then x or y may be solved before substitution.

When solving a problem listing every equation you know is usually the best way to find the correct one to use?
false
How do I find x when it's not in the equation?
I am not entirely sure what situation you are talking about. If there is no "x" in an equation, there is no point in finding it. On the other hand, if "x" disappears when solving an equation, that's usually an indication that the equation is always true, or always false, independently of the value of "x". Example: x = x + 1 Subtracting "x" from both sides, you get: 0 = 1 Since this is false, the equation is false (for ANY value of "x"). As another example: 3x = 3x Subtracing 3x on each side, you get: 0 = 0 Since this is true, and "x" doesn't appear in it, the original equation is ALWAYS true, i.e., no matter what value "x" has.
How do you know when an equation has no solution?
when you're really good in that kind of equation, but cannot, no matter what u do, CANNOT figure it out! when you look it up and can't find the answer in the back of the book. It depends on what kind of problem it is.

Community problem solving is consistent with traditional incident-driven policing. True or False?
false
Is this equation true or false 3 x - 4 Is?
False because it does not have an equality sign and so therefore it is not an equation.

True or false genes in the same linkage group are usually inheriter separatly?
i think is substitution
Is it true or false that mutations that result from the substitution of the nitrogen base for another are called deletions?
TRUE
Subscripts can be changed in order to balance a chemical equation.?
false
True or false The substitution of one nucleotide for another in the gene never affects the function of the protein?
true
Is this equation True False or Open 3x-4?
False because without an equality sign the given expression can't be considered to be an equation.
True or false given a linear equation in two variables x and y the x intercept is found by setting x equal to zero and solving for y?
False. To find the x-intercept, let y = 0 and solve for x. To find the y-intercept, let x = 0 and solve for y.
