Question

Y =C + I +G
C = 25+6 akar Y
I= 16,G = 14
contoh ye dan ce nya ?

Answer 1

Y=C+I+G
C = 25+6√Y
I= 16
G = 14

Y=C+16+14
  =C+30

C=25+6√(C+30)
C-25=6√(C+30)
(C-25)²=36(C+30)
C²-50C+625=36C+1080
C²-86C-455=0
(C-91)(C+5)=0
C-91=0 ATAU C+5=0
C=91                C=-5

Y=91+30 ATAU Y= -5+30
Y=121               Y = 25
