pertama menemukan tempat di mana dua persamaan mencegat<span>
2x+5y=1
x-3y=-5
</span>
kalikan persamaan kedua ( x - 3y = -5 ) oleh -2
-2x+6y=10
<span>tambahkan dua persamaan bersama-sama
2x+5=1

11y=11
<span>membagi kedua sisi dengan 11
y=1

subsitute y = 1 untuk y dalam semua persamaan untuk memecahkan x
x-3y=-5
x-3(1)=-5
x-3=5
x=8

x=8
y=1
(x,y)
