Tentukan himpunan penyelesaian dari 3x+2y=8 dan x-5y=-37 dengan metode subtitusi

3x + 2y = 8 ......(1)
x - 5y = -37 ......(2)

3x + 2y = 8
2y = 8 - 3x
y = 4 - 3/2x

x - 5y = -37
x - 5(4 - 3/2x) = -37
x - 20 + 15/2x = -37
x + 15/2x = -37 + 20
17/2x = -17
x = -17 / 17/2
x = -17 × 2/17
x = -34/17
x = -2

x - 5y = -37
-2 - 5y = -37
-5y = -37 + 2
-5y = -35
y = 7

HP = {(-2, 7)}
