( x - 45 ) x 27 = 0
( x - 45 ) = 0 : 27
x - 45 = 0
x = 0 + 45
x = 45
( X - 45 ) x 27 = 0
X - 45 = 0 : 27
X - 45 = 0
X = 0 + 45
X = 45
\(\left(x-45\right)\times27=0\)
\(\left(x-45\right)=0\)
\(x=45\)
( x - 45 ) x 27 = 0
x - 45 = 0 : 27
x - 45 = 0
x = 0 + 45
x = 45
Vậy x = 45
(x-45)x27=0
=>x-45=0:27
=>x-45=0
=>x=0+45
=>x=45
(X-45)x27=0
X-45 =0:27
X-45 =0
X =0+45
X =45
