\(x \times 27 + x \times 83 = 23400\)
`x \times (27 + 83) = 23400`
`x \times 110 = 23400`
`x = 23400 \div 110`

`x = 76`
Vậy, `x = 76.`

a) \(x\times27+x\times83=23400\)
\(x\times\left(27+83\right)=23400\)
\(x\times110=23400\)
\(x=23400:110\)
\(x=\dfrac{2340}{11}\)
b) \(x\times153-x\times53=7600\)
\(x\times\left(153-53\right)=7600\)
\(x\times100=7600\)
\(x=7600:100\)
\(x=76\)
