\(\left(x-2\right)\times3-270:45=120\)
\(\Rightarrow3x-6-6=120\)
\(\Rightarrow3x=120+6+6\)
\(\Rightarrow3x=132\)
\(\Rightarrow x=44\)
\(\left(x-2\right)\cdot3-270:45=120\)
\(\left(x-2\right)\cdot3-6=120\)
\(\left(x-2\right)\cdot3=120+6\)
\(\left(x-2\right)\cdot3=126\)
\(x-2=126:3\)
\(x-2=42\)
\(x=42+2\)
\(x=44\)
( 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
\(180-\left(x-45\right)\div2=120\)
\(\left(x-45\right)\div2=180-120\)
\(\left(x-45\right)\div2=60\)
\(x-45=60\times2\)
\(x-45=120\)
\(x=120+45\)
\(x=165\)

\(\left(2009-x\right)\div29=100-32\)
\(\left(2009-x\right)\div29=68\)
\(2009-x=68\times29\)
\(2009-x=1972\)
\(x=2009-1972\)
\(x=37\)

\(\left(x+x+x+..+x+x\right)+\left(0,2+0,7+1,2+...+4,2+4,7\right)=65,5\)
\(10x+\frac{\left(0,2+4,7\right)\times10}{2}=65,5\)
\(10x+24,5=65,5\)
\(10x=65,5-24,5\)
\(10x=41\)
\(\Rightarrow x=4,1\)
a: (x-35)-120=0
=>x-35=120
=>x=120+35=155
b: 59(x-29)=0
=>x-29=0
=>x=29
c: 2x+3x=45:3
=>5x=15
=>x=3
`@` `\text {Ans}`
`\downarrow`
`(x - 35) - 120 = 0`
`x - 35 = 0 + 120`
`x - 35 = 120`
`x = 120+ 35`
`x = 155`
Vậy, `x = 155`
____
`(x - 29)*59 = 0`
`x - 29 = 0 \div 59`
`x - 29 = 0`
`x = 0 + 29`
`x = 29`
Vậy, `x= 29`
____
`2x + 3x = 45 \div 3`
`(2 + 3)x = 15`
`5x = 15`
`x = 15 \div 5`
`x = 3`
Vậy, `x = 3.`
180 - ( x - 45 ) : 2 = 120
(x-45):2 =180-120
(x-45):2 =60
x-45 =60.2
x-45 =120
x =120+45
x =165
mjk nhé
180 - ( x - 45 ) : 2 = 120
( x - 45 ) : 2 = 180 - 120
( x - 45 ) : 2 = 60
x - 45 = 60 x 2
x - 45 = 120
x = 120 + 45
x = 165
sai đề nhà bạn
dư đấy
à bạn bạn chuyển số 2170 thành 270 nha>3
