Question

a) X x 27 + X x 83 = 23400 b) X x 153 - X x 53 = 7600 Giải giúp mình với ạ😢

Answer 1

`@` `\text {Ans}`

`\downarrow`

`a)`

\(x \times 27 + x \times 83 = 23400\)

`x \times (27 + 83) = 23400`

`x \times 110 = 23400`

`x = 23400 \div 110`

`x = 2340/11`

Vậy, `x = 2340/11`

`b)`

`x \times 153 - x \times 53 = 7600`

`x \times (153 - 53) = 7600`

`x \times 100 = 7600`

`x = 7600 \div 100`

`x = 76`

Vậy, `x = 76.`

Answer 2

a: =>x*110=23400

=>x=2340/11

b: =>100x=7600

=>x=76

Answer 3

a) \(x\times27+x\times83=23400\)

\(x\times\left(27+83\right)=23400\)

\(x\times110=23400\)

\(x=23400:110\)

\(x=\dfrac{2340}{11}\)

b) \(x\times153-x\times53=7600\)

\(x\times\left(153-53\right)=7600\)

\(x\times100=7600\)

\(x=7600:100\)

\(x=76\)
