Jika akar akar SPLDV 2x+3y=4 dan 3x+2y= - 1 adalah x =a dan y = b, maka a + b = (TOLONG DI BANTU KAK)

2x + 3y = 4 (x3)
3x + 2y =-1 (x2)
eleminasi X

6x + 9y = 12
6x + 4y = -2
___________-
5y = 14
y= 14/5

2x + 3y = 4
2x + 3(14/5) = 4
2x + 42/5 = 4
2x = 4-42/5
2x = 20/5 -42/5
2x = -22/5
x = -22/5/2
x= -22/10
x= -11/5

a+b
= 14/5+(-11/5)
14/5-11/5
= 3/5
