Answer:
<h2>Explanation:</h2>We have the following System of Linear Equations in two variables:
So let's call this as SYSTEM A. Two systems of equations are said to be equivalen if and only if they have the same solution, so we can get an equivalent system, called SYSTEM B, by multiplying an equation by some constant value. Let's say we multiply equation (1) by 2, then:
In conclusion:
SYSTEM A:
SYSTEM B:
SYSTEM A and SYSTEM B are equivalent

The linear combination method is the same as the elimination method. Let's multiply the second equation by -2 so the x terms cancel each other out. When we do that we get a system of 
and 
. The x-terms cancel each other out giving us 
and y = -3. Now sub -3 into one of the equations to solve for x. x+2(-3)=-4, and x - 6 = -4. x = 2. So the solution for our system is (2, -3)
