Chúc bạn học tốt! (^ _ ^)
x.7=85+100
x.7=185
x=\(\frac{185}{7}\)
vậy x=\(\frac{185}{7}\)
x.47=49-2
x.47=47
x=1
vậy x=1
<=>x.7=185
<=>x =185:7
vậy x=185/7
<=>x.47=47
<=>x =47:47=1
Vậy x=1
\(x\cdot7=85+100\)
\(\Rightarrow7x=185\)
\(\Rightarrow x=\frac{185}{7}\)
\(x\cdot47=49-2\)
\(\Rightarrow47x=47\)
\(\Rightarrow x=1\)

1) x . 7 = 85 + 100
x . 7 = 185
x = 185 : 7 ( Tìm thừa số )
x = \(\frac{185}{7}\)
2) x . 47 = 49 - 2
