himpunan penyelesaian dari 2(x+1)-3y=5 dan 3x-2(y+3)=1 adalah

Langsung aja y

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

3x - 2(y+3) = 1
3x - 2y - 6 = 1
3x - 2y = 7

2x - 3y = 3 ------ ×2
3x - 2y = 7 ------ ×3

4x - 6y = 6
9x - 6y = 21
_________-
-5x = -15
x = 3

2x - 3y = 3
3y = 2(3) - 3
3y = 3
y = 1
