x-y=0 dan 1/3x+1/2y=5 tentukan penyelesaian sistem persamaan subtitusi dan eliminasi

x - y = 0
[tex] \frac{1}{3}x + \frac{1}{2}y = 5 \\ \\ dikali \: 6 \\ \\ 2x + 3y =30 [/tex]
Subtitusi =
x - y = 0
x = y

2x + 3y = 30
2(y) + 3y = 30
5y = 30
y = 6

x - y = 0
x - 6 = 0
x = 6

Eliminasi =
2(x - y = 0)
1(2x + 3y = 30)

2x - 2y = 0
2x + 3y = 30
__________-
-5y = -30
y = 6

x - y = 0
x - 6 = 0
x = 6
