Question

46 phẩy 2 cộng x trừ 13phẩy 9=50phẩy 26

Answer 1

46, 2 + x - 13, 9 = 50, 26

46, 2 + x = 50, 26 + 13, 9

46, 2 + x = 64, 16

x = 64, 16 - 46, 2

x = 17, 96

Answer 2

\(46,2+x-13,9=50,26\)

\(\Rightarrow x-13,9=50,26-46,2\)

\(\Rightarrow x-13,9=4,06\)

\(\Rightarrow x=4,06+13,9\)

\(\Rightarrow x=17,96\)

Answer 3

46,2+x-13,9=50,26

x-13,9= 50,26-46,2

x-13,9= 4,06

x= 4,06+13,9

x=17,96
