How do you solve equations with varibles on both sides?
You have to put both variables on one side. If the question was 6x-2=x+13 then you would need to subtract the x from the side after the equals sign, and if you do something to one side to do the other. so now your question is 5x-2=13, which is a regular two step equation. just add 2 to each side, then divide 5. x should equal 3 in this example problem.
What are varibles?
A variable is something that can be changed.In Math.x+10= 15x is the variable, which can be replaced by 5.In an experiment:How do maggots appear on a piece of meat?You will need a controlled.And a Variable.Controlled: Kept in a Sealed Jar.Variable: will be kept on the open, just on a table.Then to compare it, you will need another variable, there are 2 variables.Controlled: sealed JarVariable: Inside a Jar with holes on it.You will find that the Sealed jar does not contain any maggots because the flies cannot get to the meat.And the variables will prove that since the flies had some type of access to it, there will be maggots.
Is it possible tofind three unknowns with two equations?
Answerno. A system with two equations and three variable is known as a parametric equation and can be simplified, generally, to one equation with two variables.You always need a number of equations equal to or greater than the number of variables you have to find any of the variables.If you have more varibles than equations you can eliminate a number of variables equal to the number of equations minus one.Edit: While this is correct, you can fudge an answer using a pseudoinverse. This minimizes one of the values, and then you can approximate the other two. Suppose you have:3x + 2y + 4z = 0x + 8y + 7z = 3You can call this A*b = y, whereA = [3,2,4;1,8,7]b = [x;y;z]y= [0;3]Then you can sayb=ay, wherea=A'(A*A')^(-1)' indicated the transpose, and ^-1 indicates the inverse.More explanation can be found at http://neurotheory.columbia.edu/~ken/math-notes/sabes.pdf
How do you solve systems of equations using substitution in pre-algebra?
cant explain it but i can give you an example: equation 1: 14x+2y=20 equation 2: 5x-y=8 First step is to get on of the varibles to cancel out so leave the first eqation alone put change the second in this problem so: 5x-y=8 becomes 2(5x-y=8) which equals 10x-2y=16 the next step is to subtract them like this: 14x+2y=20 10x-2y=16 the +2y and the -2y cancel out so the answer then would be 4x=4 which means 1=x then you plug the answer 1 in for x into on of the equations to find y so: 5(1)-y=8 = 5-y=8 =-y=3 =y=-3 so the system answer is (1,-3)
Which graph demonstrates a relationship between the varibles?
That one on the left.
A data table depicts the relationship between two or more?
between two or more varibles
What are independent varibles and dependent varibles?
Independent varible is what the person changed.Dependent varible is what is the same.
Do algebraic expresions have answers?
only if they have keys that tell you what the varibles mean..... but in high school they teach you a way to find the answer but put the varibles as an exponent
An equation with one or more varibles?
It is still an equation.
What variable changes to test the hypothesis?
independent varibles
What terms are other names for the y coordinate?
varibles
What is it called when finding the value of an expression by replacing the varibles with numerals?
Evaluating it.
What are identifying variables?
the variable which can be identified by the programmer are called identified varibles

How much is a 1 carat diamond Bezel worth?
too many varibles to answer
-8x plus 4y equals 64?
This can't be solved. You have two varibles.
