Question

Tolong pakai caranya ya,
terimakasih:)

Answer 1

X/2 + y/5 = 13/5
  5x + 2y = 26..........1

x/3 - 2y/5 = 2/15
    5x - 6y = 2............2

eliminasi x dari pers 1 dan 2:
5x + 2y = 26
5x - 6y  =  2 (-)
        8y = 24
          y = 3, maka x= (26-6)/5
                              x= 4...................opsi D
