Is there solution for this kind of equation

In summary: Since each equation has two unknowns, you can only get at most 2 equations with 2 unknowns, so you can't solve the 10 equations. Therefore, in summary, it is not possible to find the values of X and Y in this scenario.

to solve this question is possible or not

X1Y1 = A

X2Y2 = B

X3Y3 = C

X4Y4 = D

X4Y5 = E

HERE A,B,C,D, and E known. X and Y ` s unknown. if you divide

X1Y1 / X2Y2 = A/B
X1Y1 / X3Y3 = A/C
X1Y1 / X4Y4 = A/D
X1Y1 / X5Y5 = A/E
X2Y2 / X3Y3 = B/C
X2Y2 / X4Y4 = B/D
X2Y2 / X5Y5 = B/E
X3Y3 / X4Y4 = C/D
X3Y3 / X5Y5 = C/E
X4Y4 / X5Y5 = D/E

we have 10 equation and 10 unknown, may I ask can we find each X and Y values. is iy possible.

thanks

By X1, I assume you mean X1 and similarly for the rest. Each of your original equations are independent of each other.
In the derived equations, even though you seem to have 10 independent equations and 10 unknowns, when solving you will find that these are in fact dependent, therefore a solution is not possible.

To show arunbg's point: if you divide the last two equations,
X3Y3 / X5Y5 = C/E
X4Y4 / X5Y5 = D/E
you get
X3Y3 / X4Y4 = C/D
which is already in the list.
No matter how you rewrite it, you will keep 5 independent equations for the 10 unknowns.
 

1. What is an equation?

An equation is a mathematical statement that shows the relationship between two or more quantities. It consists of numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division.

2. What is a solution to an equation?

A solution to an equation is a value or set of values that satisfy the equation and make it true. It is the value that makes both sides of the equation equal.

3. How do you solve an equation?

To solve an equation, you need to isolate the variable on one side of the equation by performing the same mathematical operation on both sides. The goal is to get the variable alone on one side and the numbers on the other side.

4. Is there a universal method for solving all types of equations?

No, there is no one-size-fits-all method for solving equations. The method used depends on the type of equation and the mathematical operations involved. Some common methods include the use of inverse operations, factoring, and substitution.

5. Are there equations that do not have solutions?

Yes, there are equations that do not have solutions. These are called inconsistent equations, and they occur when the solution leads to a contradiction or an impossible statement. For example, the equation 2x + 5 = 2x + 10 has no solution because it leads to the statement 5 = 10, which is not true.
