How do you solve this linear system using elimination 2x-3y equals -2 4x plus y equals 24?
2X - 3Y = -2
4X + Y = 24
-2(2X - 3Y = - 2)
4X + Y = 24
- 4X + 6Y = 4
4X + Y = 24
------------------+
7Y = 28
Y = 4
-------
insert back into one of the equations ( 4X + Y = 24 will do )
4X +(4) = 24
4X = 20
X =5
--------
check
2(5) - 3(4) = -2
10 - 12 = -2
-2 = -2
checks
I can see by inspection that the other equation checks also

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.
When should you use multiplication to solve a system of linear equations by elimination?
You should use multiplication to solve a system of linear equations by elimination when the coefficients of one variable in the two equations are not easily aligned for direct elimination. This often occurs when the coefficients are not opposites or when they are not easily manipulated to create a zero in one of the variables. By multiplying one or both equations by a suitable value, you can create equal or opposite coefficients, allowing you to eliminate one variable and solve the system more efficiently.
How can you solve a linear equation?
by elimination,substitution or through the matrix method.

What are two symbolic techniques used to solve a system of linear equations in two variables?
I have never seen the term 'symbolic' used in this way. There are 4 methods used to solve a system of linear equations in two variables. Graphing, Substitution, Elimination, and Cramer's Rule.
Linear Systems and Functional Approximation Solve the equation Ax equals b for x by calculating an LU decomposition of A back Solving where A equals 2 1 1 and b equals 2 11?
The linear system is a math model of a system that is based on the use of a linear operator. The linear system and functional approximation to solve the equation Ax equals b for x by calculating an LU decomposition of A back solving where A equals 2 1 1 and b equals 2 11 cannot be solved, because it is missing more information.
