See below

$x=1/2" " y=-1/2$

$y=−3x+1;5x−2=−y" "$ this is the same as

$y=−3x+1"$
$−y=5x−2" "$ Now add these two equations

$0=2x-1" " rArr1=2x" "$ Divide both sides by $2$

$x=1/2" "$ Substitute this into the first equation

$y=-3*1/2+1" "rArry=-1/2$

$x=1/2" " y=-1/2$

How do you solve this system of equations: y= - 3x + 1; 5x - 2= - yy= - 3x + 1; 5x - 2= - y?
