Himpunan penyelesaian dari 3× – 2y – 8 = 0 dan 4× + y – 7= 0 adalah

3x – 2y = 0+8
x. = 8
Hp = 8

4x + x = 0+7
5 x = 7
x = 7:5
x = 1,2
Hp = 1,2

Eliminasi x

3x – 2y = 8 (×4)
4x + y = 7. (×3)

12x – 8y = 32
12x + 3y = 21
____________-
-11y = 11

y = 11 ÷ -11

y = -1

eliminasi y

3x – 2y = 8

3x -2 × -1 = 8

3x + 2 = 8

3x = 8 – 2

3x = 6

x = 6 ÷ 3

x = 2
