\(17x=69.17-17.67\)
\(\Leftrightarrow17x=17.\left(69-67\right)\)
\(\Leftrightarrow17x=17.2\)
\(\Leftrightarrow x=2\)
\(17x=69\times17-17\times67\)
Xét vế sau ta có:
\(69\times17-17\times67\)
\(=\left(69-67\right)\times17\)
\(=2\times17\)
\(=34\)
Ta lại có: \(17x=34\)
\(\Rightarrow x=34:17\)
\(\Rightarrow x=2\)
Vậy \(x=2\)
17x=69.17-17.67
17x=17.(69-67)
17x=17.2
17x=34
x=34:17
x=2
vậy x=2
17x = 17.(69-67)
17x =17.2
17x = 34
x =34:17
x=2
Vậy x bằng 2
\(17x=69.17-17.67\)
\(17x=17\left(69-67\right)\)
\(\)\(x=2\)
17x = 69*17 - 17*67
17x = 17(69-67)
17x = 17*2
17x = 34
x = 34 : 17
x = 2
Vậy x = 2
