Question

65-5[x+11]=10    

giải giùm mik nha 

Answer 1

65- 5( x+11) =10

=> 5( x+11) = 65- 10

=> 5( x+11) = 55

=> x+ 11= 55: 5

=> x+ 11= 11

=> x= 11- 11

=> x= 0

Vậy x= 0

 

Answer 2

\(65-5\left\{x+11\right\}=10\\ =>5\left\{x+11\right\}=55\\ =>x+11=11\\ =>x=0\)

Answer 3

65-5( X+11)=10

\(\Leftrightarrow\)5( X+11)=65-10

\(\Leftrightarrow\)5(X+11)=55

\(\Leftrightarrow\)X+11=55\(_{\div}\)5

X+11=11

X=0
