9x-9y = 36 => x-y = 4
3(-y+x = 4)
7y-3x = -14
Multiply all terms in the top equation by 3:
-3y+3x = 12
7y-3x = -14
Add both equations together:
4y = -2
Divide both sides by 4:
y = -0.5
Substitute the value of y into the original equations to find the value of x:
x = 3.5 and y = -0.5
What else can I help you with?
Y equals x plus 3 and 3x-y equals 5?
Solve this simultaneous equation using the elimination method after rearraging these equations in the form of: 3x-y = 5 -x+y = 3 Add both equations together: 2x = 8 => x = 4 Substitute the value of x into the original equations to find the value of y: So: x = 4 and y = 7
What are the pros and cons of using the substitution or elimination method in equations?
Oh, dude, like, the substitution method is cool because you can easily solve for one variable and plug it into the other equation. But, like, it can get messy with fractions and decimals. The elimination method is great for getting rid of one variable right away, but it can be a pain to keep track of all those plus and minus signs. So, like, pick your poison, man.
How do you solve 3x2 x-4 equals 0?
3x2+x-4 = 0 (3x+4)(x-1) = 0 Solutions: x = 1 and x = -4/3 By using the quadratic equation formula.
What are the limitations of regula falsi method?
Limitations of Regular falsi method: Investigate the result of applying the Regula Falsi method over an interval where there is a discontinuity. Apply the Regula Falsi method for a function using an interval where there are distinct roots. Apply the Regula Falsi method over a "large" interval.
How do you solve the equation by using the zero element?
Not sure what you mean by "zero element". If an expression is equal to zero, and you can factor it, then at least one of the factors must be zero; this is often useful to solve an equation.
How do you solve y equals 2x-6 and 3x plus y equals 4 using the elimination method?
(2,-2)
Solve the system of equations using the elimination method negative x plus y equals negative 3 and 3x plus 2y equals 9?
By elimination: x = 3 and y = 0
Can You Solve 2x plus 3y equals 18 and 2x-3y equals -6 Using The Elimination Method?
Yes and it works out that x = 3 and y = 4
Can quadratic systems be solved using elimination and substitution?
You can solve lineaar quadratic systems by either the elimination or the substitution methods. You can also solve them using the comparison method. Which method works best depends on which method the person solving them is comfortable with.
How do you solve using elimination method 2x-y equals -2?
4
How do you solve 0.2x plus 4y equals -1 by using Elimination?
You cannot solve one linear equation in two variables. You need two equations that are independent.
How do you solve systems of equations by using elimination?
Multiply every term in both equations by any number that is not 0 or 1, and has not been posted in our discussion already. Then solve the new system you have created using elimination or substitution method:6x + 9y = -310x - 6y = 58
The ELIMINATION method performs operations on a system of equations to?
Simultaneous equations can be solved using the elimination method.
Solve using susbstitution method X-5y equals -54 and 2y-5x equals 63?
8840-026
How do you Solve this system of equations using the addition method 6a - 5b equals 9 2a plus 5b equals 23?
the answer
4x-7y equals 13 -2x plus 7y equals -3?
One way to solve this system of equations is by using matrices. Form an augmented matrix in which the first 2x2 matrix is the coefficient matrix and the 2x1 matrix on its right is the answer. Now apply Gaussian Elimination and back-substitution. Using this method gives x=5 and y=1.
What is the disadvantage of using the substitution method in solving linear equations rather than the graph method?
There are no disadvantages. There are three main ways to solve linear equations which are: substitution, graphing, and elimination. The method that is most appropriate can be found by looking at the equation.
