\(\left(x-2\right)\times3-270:45=120\)
\(\Rightarrow3x-6-6=120\)
\(\Rightarrow3x=120+6+6\)
\(\Rightarrow3x=132\)
\(\Rightarrow x=44\)

x - 270 : 45 = 120
<=> x - 270 = 120 x 45
<=> x - 270 = 5400
<=> x = 5400 + 270
<=> x = 5670

\(\left(x-2\right)\cdot3-270:45=120\)
\(\left(x-2\right)\cdot3-6=120\)
\(\left(x-2\right)\cdot3=120+6\)
\(\left(x-2\right)\cdot3=126\)
\(x-2=126:3\)
\(x-2=42\)
\(x=42+2\)
\(x=44\)

( x - 2 ) . 3 - 270 : 45 = 120
( x - 2 ) . 3 - 6 = 120
( x - 2 ) . 3 = 120 + 6
( x - 2 ) . 3 = 126
x - 2 = 126 :3
x - 2 = 42
x = 42 + 2
x = 44

(x-15)x7-270:45=169
(x-15) x 7 - 6 = 169
(x - 15 ) x 7 = 169 + 6
( x -15) x 7 = 175
x - 15 = 175 : 7
x - 15 = 25
x = 25 + 15
x = 40
Vậy x = 40
# HOK TỐT #
(x-15) x 7 -270 : 45=169
(x-15) x 7 - 6 =169
(x-15) x 7 = 169+6
(x-15) x 7 = 175
x-15

\(\left(x-2\right)\times3-270:45=120\)
\(\Rightarrow\left(x-2\right)\times3-6=120\)
\(\Rightarrow\left(x-2\right)\times3=120+6\)
\(\Rightarrow\left(x-2\right)\times3=126\)
\(\Rightarrow x-2=126:3\)
\(\Rightarrow x-2=42\)
\(\Rightarrow x=42+2\)
\(\Rightarrow x=44\)
Vậy x = 44
