if you have one equation that gives you x or y
use substitution
x+3y=18
x= 18-3y
substitute (18-3y) for x in the other equation
if you have coefficients that will not 'reduce'
use elimination
2x+3y= -3
5x-4y=9
watch for equations that will reduce
2x+4y= -8
divide through by 2
x+2y= -4
x= -4-2y
sum is addition difference is subtraction
the inverse of addition is subtraction and the inverse of multiplication is division. Of course, multiplication is just repeated addition so division is just repeated subtraction!
What is the difference between 392 and 247?
the difference is also doubled
There is no difference in value between "equal" fractions: the difference is zero.
what is d difference between import substitution and export promotion
The difference between substitution and transposition is that in:Subtitution:each letter retains its position but changes its identity,Transposition:each letter retains its identity but changes its position.
A generic substitution is a type of congress party that is involved with various types of congress meetings. A therapeutic substitution is a massage they give in therapy.
because icup lol if u said that out loud ur dome ans i like 2 suck ****s lol but ilu sike lol byez
Subtraction involves taking away a number from another number, while addition involves combining two or more numbers to find a total sum. Subtraction results in a smaller number, while addition results in a larger number.
sum is addition difference is subtraction
Gaussian elimination as well as Gauss Jordan elimination are used to solve systems of linear equations. If, using elementary row operations, the augmented matrix is reduced to row echelon form, then the process is called Gaussian elimination. If the matrix is reduced to reduced row echelon form, the process is called Gauss Jordan elimination. In the case of Gaussian elimination, assuming that the system is consistent, the solution set can be obtained by back substitution whereas, if the matrix is in reduced row echelon form, the solution set can usually be obtained directly from the final matrix or at most by a few additional simple steps.
There is no difference between vector addition and algebraic addition. Algebraic Addition applies to vectors and scalars: [a ,A ] + [b, B] = [a+b, A + B]. Algebraic addition handles the scalars a and b the same as the Vectors A and B
well,both are different methods but the answers are same.
Elimination is carried out by 2 process - biotransformation and - excretionExcretion means complete removal of drug and its metabolites from internal nvironment to external enviroment.
One says value and the other has addition on the end.
The difference between SunIn and lemon SunIn is the addition of some form of lemon.
