(x*3)/24=305
x*3=305*24
x*3=7320
x=2440
còn gì chưa hiểu thì nhắn tin nhá
mình xin k
(x+x*2):24=305
x+x*2=305*24
1*x+2*x=7320
(1+2)*x=7320
3*x=7320
x=7320:3
x=2440
( x + x x 2 ) : 24 = 305
( x x 3 ) : 24 = 305
x x 3 = 305 x 24
x x 3 = 7320
x = 7320 : 3
x = 2440
\(\frac{\left(x+x\times2\right)}{24}=305\)
\(x+x\times2=305:24\)
\(x+x\times2=\frac{305}{24}\)
\(x\times3=\frac{305}{24}\)
\(x=\frac{305}{24}:3\)
\(x=\frac{305}{72}\)
( 2 x * 2 ) = 305 * 24
( 2 x * 2 ) = 7320
2 x = 7320/2
2 x = 3660
x = 3660/2
x = 1830
k nhá !!!!!!!!
