y+1=2xdan2y=3x-5 Berpah hasil penyelesaian

y + 1 = 2x ⏩pindah ruas: y = 2x - 1
2y = 3x - 5

y = 2x - 1 || x 2
2y = 3x -5 || x 1

=>
2y = 4x - 2
2y = 3x - 5
----------------- (dikurang biar y nya abis)
0 = x + 3
x = -3

cari y (substitusi):
y +1 = 2x
y +1 = -6
y = -7

-2x + y    = -1
-3x + 2y = -5
----------------- -

-4x +2y  = -2
-3x + 2y = -5
-----------------  -
-x = 3
x  = -3

-2x + y    = -1
6 + y = -1
y =  -7

jadi, x = -3 dan y = -7
