`2x-14=5.2^3`
`2x-14=5.8=40`
`2x=40+14=54`
`x=54:2=27`
\(2\cdot x-14=5\cdot8< =>2\cdot x-14=40< =>2\cdot x=54< =>x=27\)
\(2.x-14=5.2^3\)
\(2.x-14=5.8\)
\(2.x-14=40\)
\(2.x=14+40\)
\(2x=54\)
\(x=54:2\)
\(x=27\)
`2x-14=5.2^3`
`=> 2x-14=5.8`
`=> 2x-14=40`
`=> 2x=40+14`
`=> 2x=54`
`=> x=54:2`
`=> x=27`
Vậy `x=27`
