Có lời giải nhé

Answer 1

2018 - X x 15 + 785 = 1875

           X x 15 + 785 = 143

           X x 15 = -642

           X = -42,8

Answer 2

ta cho x là x

2018 - x x 15 + 785 = 1875

2018 - x x 15 = 1875 - 785 = 1090

x x 15 = 2018 - 1090 = 928

x = 928 : 15 = \(61\frac{13}{15}\)

Answer 3

2018-X x 15 +785=1875

=>2018- X x 15 =1875-785

=>2018- X x 15=1090

=>X x 15=2018 - 1090

=> X x 15=928

=>X=928 :15

=>X=\(\frac{928}{15}\)
