X-y=5 x+y=1 tolong carikan grafik,eliminasi dan subtitusi nya dongg
5dregensleyer
U - y =5 u + y = 1 _ eliminasi -2y = 4 y = -2 u -y = 5 subtitusi u - (-2) = 5 u + 2 = 5 u = 5-2 u = 3 maka HP = (3,-2) gambar titik u di angka 3 dan y di angka -2

X - y = 5 x + y = 1 - -2y = 4 2y = -4 y = -2 x - y = 5 x -(-2) = 5 x + 2 = 5 x = 5-2 x = 3
u + y = 1 _ eliminasi
-2y = 4
y = -2
u -y = 5 subtitusi
u - (-2) = 5
u + 2 = 5
u = 5-2
u = 3
maka HP = (3,-2)
gambar titik u di angka 3 dan y di angka -2
x + y = 1 -
-2y = 4
2y = -4
y = -2
x - y = 5
x -(-2) = 5
x + 2 = 5
x = 5-2
x = 3
