7x - 3y = 37
2x - y = 12
You can eliminate y by multiplying both sides of equation 2 by minus 3 and then add:
7x - 3y = 37
-6x + 3y = -36
x = 1
substitute x =1 into either equation and solve y
2(1) -y =12
-y = 10
y = -10
True
If you multiply or divide an equation by any non-zero number, the two sides of the equation remain equal. This property is almost always needed for solving equations in which the variables have coefficients other than 1.
x-9y
True
For a linear I can see no advantage in the table method.
by elimination,substitution or through the matrix method.
True
Yes, for solving simultaneous equations.
The elimination method only works with simultaneous equations, hence another equation is needed here for it to be solvable.
a method
Simultaneous equations can be solved using the elimination method.
There are several methods to solve linear equations, including the substitution method, elimination method, and graphical method. Additionally, matrix methods such as Gaussian elimination and using inverse matrices can also be employed for solving systems of linear equations. Each method has its own advantages depending on the complexity of the equations and the number of variables involved.
There are four steps in an algebraic elimination problem. These steps are: to find a variable with equal or opposite coefficients, if equal then subtract the equations but if opposite then add, solve one variable equation left, and then substitute known variable into other equation and solve. hi
Solution can be found by using three methods: 1. Cross Multiplication Method 2. Substitution Method 3. Elimination Method Other Method can also be there but I don't know You can further get info about these method by searching these on Google Search.
True. The elimination method is a technique used in solving systems of equations where you can eliminate one variable by adding or subtracting equations. This simplifies the system, allowing for easier solving of the remaining variable. It is particularly effective when the coefficients of one variable are opposites or can be made to be opposites.
Yes
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.
