`4(x-5)-2^3=2^{4}.3`
`=>4(x-5)-8=16.3=48`
`=>4(x-5)=48+8=56`
`=>x-5=56:4=14`
`=>x=19`
Vậy `x=19`
4.(x-5)-23=24.3
4.(x-5)-8=16.3
4.(x-5)-8=48
4.(x-5)=48+8
4.(x-5)=56
x-5=56:4
x-5=14
x=14+5
x=19
4 (x - 5) - 2³ = 2⁴*3
=> 4 (x - 5) - 2³ = 16*3 = 48
=> 4 (x - 5) = 48 + 2³ = 48 + 8 = 56
=> x - 5 = 56/4 = 14
=> x = 14 + 5 = 19
Vậy x = 19
