himpunan penyelesaian dari sistem persamaan linear berikut a. 4x + 3y = -1 3x - 2y = 0

8x + 6y = - 2
9x - 6y = 0
__________ +
17x = - 2
x = - 2/17
y = 3/17

4 x + 3 y = -1 — 8 x + 6y = - 2 3x + 2y = 0 — 9x + 6y = 0 Eliminasi y diperoleh - x = - 2 x = 2 4x + 3y = -1 4(2) + 3 y = -1 3y = -1 -8 3y = -9 y = -3 HP : { 2,-3}
