$x = 1, y = 1$ $x = 1, y = 1$

1 ) $4 x + 2 y = 6$ $4x + 2y = 6$
2 ) $x - y = 3$ $x - y = 3$

2(x2) ) $2 x - 2 y = 6$ $2x - 2y = 6$

Add the two together:

$6 x = 6$ $6x = 6$
$x = 1$ $x = 1$

Sub x value into the equation again:

$4 + 2 y = 6$ $4 + 2y = 6$
$2 y = 2$ $2y = 2$
$y = 1$ $y = 1$

What is the value of the xx variable in the solution to the system of equations 4x+2y=64x+2y=6 and x−y=3x-y=3?
