Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "divided by", "equals", "squared", "cubed" etc. Please use "brackets" (or parentheses) because it is impossible to work out whether x plus y squared is x + y^2 or (x + y)^2.

What is the solution of the system of equations y-2x 5 -5y10x 20?
Without any equality signs the given expressions can't be considered as equations.
The system of equations 3x-6y equals 20 and 2x-4y equals 3 is?
the system of equations 3x-6y=20 and 2x-4y =3 is?Well its inconsistent.
What is the solution to the system of equations given below using elimination by addition 6x 6y 36 2x - 2y 20?
If you mean: 6x+6y = 36 and 2x-2y = 20 then its works out x = 8 and y = -2
What is linear algebra used for?
Linear algebra is used to analyze systems of linear equations. Oftentimes, these systems of linear equations are very large, making up many, many equations and are many dimensions large. While students should never have to expect with anything larger than 5 dimensions (R5 space), in real life, you might be dealing with problems which have 20 dimensions to them (such as in economics, where there are many variables). Linear algebra answers many questions. Some of these questions are: How many free variables do I have in a system of equations? What are the solutions to a system of equations? If there are an infinite number of solutions, how many dimensions do the solutions span? What is the kernel space or null space of a system of equations (under what conditions can a non-trivial solution to the system be zero?) Linear algebra is also immensely valuable when continuing into more advanced math topics, as you reuse many of the basic principals, such as subspaces, basis, eigenvalues and not to mention a greatly increased ability to understand a system of equations.
What is 4x plus 8y equals 20 - -4x plus 2y equals -30?
It looks like you have 2 simultaneous equations with 2 variables:4x + 8y = 20 and -4x + 2y = -30. Solution is {x=7, y = -1}.One way to solve:Add the two equations together, combining like terms: (4x - 4x) + (8y + 2y) = 20-30 --> 0 + 10y = -10 --> y = -1. Substitute this into either of the original equations and solve for x=7, then check in the other equation to make sure you calculated correctly.

6x+7y=20Y=2x?
the solution to the system of equations 6x + 7y = 20 and y = 2x is (x, y) = (1, 2)

Use the substitution method to solve the system of equations. Choose the correct ordered pair. 2y plus 2x 20 y - 2x 4?
It is not possible to know exactly what the question is because the browser used by this site is almost totally useless for mathematical questions: it rejects most symbols. If the equations are 2y + 2x = 20 and y - 2x = 4,then the solution is (2, 8).
How many liters of 50 percent alcohol solution and 20 percent alcohol solution must be mixed to obtain 3 liters of 40 percent alcohol solution?
Let there be x litres of 50% solution and y% of 20 % solution, then you have two equations by considering the amount of alcohol and the total amount of liquid:50% x + 20% y = 40% of 3 litresx + y = 3 litresThese are two simultaneous equations involving 2 unknowns which can be solved:Double {1} and subtract from {2} to give:x - x + y - 40%y = 3 - 80% of 3→ 60% y = 20% of 3→ y = 20%/60% of 3 = 1/3 of 3 = 1Substitute for y in {2} to get:x + 1 = 3x = 2Therefore you need 2 litres of 50% solution and 1 litre of 20% solution.

What would we use system of equations for in real life?
Cindy and Dan together have 20 apples. Cindy has 2 more apples than Dan. How many apples does Dan have? That's just one of the many basic scenarios where a system of equations would come in handy.
4x-y equals 33 x plus 5y equals 24 what is the solution of the system?
The solution of the system of the two equations, 4x - y = 33 and 5y = 24 may be found by first solving the second equation for y: y = 24/5. then substituting this value into the first equation to produce 4x - (24/5) = 33, or x = [33 + (24/5)]/4 = [(189/5)/4] = (189/20).

Solution to the following system of equations 5x2 - 2y2 equals -20 7x2 - y2 equals 152?
5x2 - 2y2 = -20 7x2 - y2 = 152 Eq1 - 2*Eq2: -9x2 = -324 so that x2 = 36 Substituting the value of x2 in Eq1: 2y2 = 200 so that y2 = 100 The four solutions are (-6, -10), (-6, 10), (6, -10) and (6,10)
