how did you solve it??? I get x=((19)/5) and y=((21)/5)
howdidyousolveit???Igetx=195andy=215

how could it be x=y=5 when x+y=8? how could it be x=(7/5) and y=((13)/5) when x+y=8?

thank for answer bro i got the solution like this. im so stupid sorry for that question guys x+y= 8 x=8−y 2×(8−y)−3y=−5 16−2y−3y=−5 5y=−5−16 y= ((−21)/(−5)) x= 8−((21)/5) x= ((19)/5)

x + y = 8 −−−(1) 2x − 3y = −5 −−−(2) (1)×2: 2x + 2y = 16 −−−(3) (2)×1: 2x − 3y = −5 −−−(4) (3) − (4): 5y = 21 ⇒ y=((21)/5) Sub in (1) x + ((21)/5) = 8 x = 8−((21)/5) x = ((40−21)/5) x = ((19)/5) (x,y) = (((19)/5),((21)/5))
x+y=8−−−(1)2x−3y=−5−−−(2)(1)×2:2x+2y=16−−−(3)(2)×1:2x−3y=−5−−−(4)(3)−(4):5y=21⇒y=215Subin(1)x+215=8x=8−215x=40−215x=195(x,y)=(195,215)
