4x-2y = 6
-7x+2y = -15
Add both equations together in order to eliminate y:
-3x = -9
Divide both sides by -3 in order to find the value of x:
x = 3
Substitute the value of x into the original equations to find the value of y:
Solution: x = 3 and y = 3

How do you decide whether to use elimination or subsitution to solve a three-variable system?
There is no simple answer. Sometimes, the nature of one of the equations lends itself to the substitution method but at other times, elimination is better. If they are non-linear equations, and there is an easy substitution then that is the best approach. With linear equations, using the inverse matrix is the fastest method.

What is the elimination methods?
A method for solving a system of linear equations; like terms in equations are added or subtracted together to eliminate all variables except one; The values of that variable is then used to find the values of other variables in the system. :)

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.
What type of system of linear equation is y equals -3x-1 and 3x plus -1?
A consistent system.
