Question

Tìm x

(x\(\times\)5)+(x\(\times\)2)+(x\(\times\)3)=100

 

Answer 1

x\(\times\)(5+2+3)=100

x\(\times\)10=100

x=100\(\div\)10=10

Vậy x =10

Answer 2

\(\left(x\times5\right)+\left(x\times2\right)+\left(x\times3\right)=100\)

=> \(x\times\left(5+3+2\right)=100\)

=> \(x\times10=100\)

=> \(x=100\div10=10\)
