#### Answer

$x=1$
$y=2$

#### Work Step by Step

Equation 2 is already solved for y, we substitute y in the first equation, with the expression in the second:
$4x+y=6$
$4x+2x=6$
$x=1$
$y=2x=2$
We need to check, if it is the right solution, we substitute x with 1 and y with 2:
$4(1)+2=6$ $\checkmark$
$2=2(1)$ $\checkmark$
