3x-2y=-7 (x2) 6x-4y=-14 (dikurangkan)
-11y = 44
y = -4
Substitusikan nilai y ke persamaan (1)
2x - 5y = 10
2x - 5 (-4) = 10
2x + 20 = 10
2x = -10
x = -5
3x - 2y = -7 x2 6x - 4y = -14
----------------- -
-11y = 44
y =
y =- 4
2x - 5y = 10
2x - 5.-4 = 10
2x + 20 = 10
2x = 10 - 20
2x = -10
x =
x = -5
Semoga Membantu....
