Question

( x - 35 ) - 120 = 0

124 + ( 118 - x ) = 217

156 - ( x + 61 ) = 82

giúp mình với ạ

Answer 1

`a, => x - 35 = 120`

`=> x = 155`

`b, => 118 - x = 93`

`=> x = 25`

`c, => x + 61 = 74`

`=> x = 13`

Answer 2

\(a,\left(x-35\right)-120=0\)

\(x-35=0+120=120\)

\(x=120+35=155\)

 

\(b,124+\left(118-x\right)=217\)

\(118-x=217-124=93\)

\(x=118-93=25\)

 

\(c,156-\left(x+61\right)=82\)

\(x+61=156-82=74\)

\(x=74-61=13\)
