Selesaikan sistem persamaan 2x-3y-13=0 dan 2x+7y-3=0 dengan cara metode eliminasi adalah?????

eliminasi x
2x + 7y - 3 = 0
2x - 3y - 13 =0
___________-
10y + 10 = 0
10y = -10
y = -1

eliminasi y
2x - 3y - 13 =0 |×7
2x + 7y - 3 = 0 |×3
14x - 21y - 91 = 0
6x + 21y - 9 = 0
_____________+
20x - 100 =0
20x = 100
x = 5
