Question

\(\dfrac{1}{10}x+\dfrac{1}{15}\left(11-x\right)=1\)

giải pt hộ mik ạ

Answer 1

`1/10x+1/15(11-x)=1`

`<=>1/10x+11/15-1/15x=1`

`<=>1/30x=1-11/15=4/15`

`<=>x=4/15*30=8`

Vậy `x=8`

Answer 2

\(\dfrac{x}{10}+\dfrac{11-x}{15}=1< =>\dfrac{3x+22-2x}{30}=1\)

\(< =>\dfrac{3x+22-2x}{30}=1=>x+22=30< =>x=30-22< =>x=8\)
