Question

( 2. x+18). 2+43= 103

Answer 1

\(\left(2x+18\right).2+43=103\)

\(\left(2x+18\right).2=103-43\)

\(\left(2x+18\right).2=60\)

\(2x+18=60:2\)

\(2x+18=30\)

\(2x=30-18\)

\(2x=12\)

\(x=6\)

Answer 2

`( 2x + 18 ) . 2 + 43 =103`

`( 2x + 18 ) . 2 = 103 - 43`

`( 2x + 18 ) . 2 = 60`

`2x + 18 = 60 : 2`

`2x + 18 = 30`

`2x = 30 - 18`
`2x = 12`
`x =12 : 2`
`x = 6`
Vậy, `x = 6`
