Systems of equations that have the same solution are called equivalent systems. We can produce an equivalent system by replacing one equation by the sum of the two equations, or by replacing an equation by a multiple of itself.
1/3x+y=5/4
and
2x-4y=5
Now we use elimination
y=-1/3x+5/4
-4y=4/3x-5
4/3x+4y=5
and
2x-4y=5
Eliminate the y's,
10/3x=10
10x=30
x=3
Plug into other equation
2x-4y=5
2(3)-4y=5
6-4y=5
1=4y
y=1/4
