Question

5x- 2y= -14
8x- 5y=-17

Answer 1

5x- 2y= -14 ...... I (5)
8x- 5y= -17 ....... II (-2)

25x-10y = -60
-16x+10y = +34
''''''''''''''''''''''''''''''''
9x = -26
x × -26/9 ......III

III en I

5x-2y = -14
5(-26/9) -2y = -14
-130/9 +14 =2y
(-130+ 126)/9 =2y
-4/9 = 2y
-4/18 = y
-2/9 = y

CS= ( -26/9; -2/9)
