Question

95,13 x a + 2,07 x a = 972

Answer 1

`95,13 xx a + 2,07 xx a = 972`

`=>(95,13 + 2,07)xx a = 972`

`=>97,2xx a = 972`

`=>x=972 : 97,2`

`=>x=10`

Answer 2

\(95,13a+2,07a=972\)

\(\Rightarrow\left(95,13+2,07\right)a=972\)

\(\Rightarrow97,2a=972\)

\(\Rightarrow a=972:97,2=10\)

Vậy \(a=10\)

Answer 3

\(95,13\times a+2,07\times a\text{=}972\)

\(\left(95,13+2,07\right)\times a\text{=}972\)

\(97,2\times a\text{=}972\)

\(a\text{=}972:97,2\)

\(a\text{=}10\)
