18*(x-160)=18

Answer 1

a/ \(\left(x-34\right).15=0\)

\(\Leftrightarrow x-34=0\)

\(\Leftrightarrow x=34\)

Vậy .....

b/ \(18\left(x-160\right)=18\)

\(\Leftrightarrow x-160=1\)

\(\Leftrightarrow x=161\)

Vậy ...

Answer 2

1. \(\left(x-34\right).15=0\)

\(x-34=0:15\)

\(x-34=0\)

\(x=0+34\)

\(x=34\)

Vậy \(x=34\)

2. \(18.\left(x-160\right)=18\)

\(x-160=18:18\)

\(x-160=1\)

\(x=1+160\)

\(x=170\)

Vậy \(x=170\)

Answer 3

x = 170

Đúng ko

Answer 4

x-34 = 0/15

x-34 = 0

x = x0+34

x = 34

x-160=18/18

x-160=1

x=1+160

x=161
