13x - 130 = 65
13x = 65 + 130
13x = 195
x = 195 : 13
x = 15
k mình nha
13x - 130 = 65
13x = 65 + 130
13x = 195
x = 195 : 13
x = 15
nha bn
=> 13x=130+65
=> 13x=195
=> x=195:13
=>x=15
tíc mình nhoa
\(13x-130=65\)
\(13\times\left(x-10\right)=65\)
\(x-10=65\div13\)
\(x-10=5\)
\(x=5+10\)
\(x=15\)
13x - 130= 65
13x = 65+130
13x = 195
x = 195:13
x = 15
13x-130=65
13x =65+130
13x =195
x =195:13
x=15
Vay x can tim la:15
