60+24:(x+1)=28
84:(x+1)=28
x+1=84:28
x+1=3
x=3-1=2
60 + 24: [ x + 1 ] = 28
24 : [ x + 1 ] = 28 - 60
24 : [ x + 1 ] = - 32
x + 1 = 24 : ( - 32 )
x + 1 = \(\frac{-3}{4}\)
x = \(\frac{-3}{4}\)+ 1
x = \(\frac{1}{4}\)
60 + 24 : ( X + 1 ) = 28
84 : ( X + 1 ) = 28
X + 1 = 84 : 28
X + 1 = 3
X = 3 - 1
X = 2
Mình chưa chắc đã đúng đâu !
\(60+24:\left(x+1\right)=28\)
\(24:\left(x+1\right)=28-60\)
\(24:\left(x+1\right)=-32\)
\(x+1=24:\left(-32\right)\)
\(x+1=-0.75\)
\(x\) \(=-0.75-1\)
\(x\) \(=-1,75\)
60+24:(x+1)=28
(=) 24:(x+1)= 60-28
(=) 24:(x+1)= 32
(=) x+1= 24:32
(=) x+1= 3/4
(=) x= 3/4-1
(=) x= 3/4-4/4
(=) x= -1/4
Vậy x= \(\frac{-1}{4}\)
