#Học tốt
a) 145- (125+x)=12
b) 5(x+12) +22=92
tik mk nha mk sẽ tik lại,làm câu kết luận luôn nha!!!!!!!!!thanks
a) 145 - ( 125 + X ) = 12
125 + X = 145 - 12
125 + X = 133
X = 133 - 125
X = 8
Vậy X = 8
b) 5.( X + 12 ) + 22 = 92
5.( X + 12 ) = 92 - 22
5.( X + 12 ) = 70
X + 12 = 70 : 5
X + 12 = 14
X = 14 - 12
X = 2
Vậy X = 2
Học tốt #
a) 145-(125+x)=12
125+x=145-12
125+x=133
x=133-125
x=8
Vậy x = 8
b) 5(x+12)+22=92
5(x+12)=92-22
5(x+12)=70
x+12=70:5
x+12=14
x=14-12
x=2
Vậy x = 2
mk nha mn
\(a) 145-(125+x)=12\)
\(=> 125+x=145-12\)
\(=> 125+x=133\)
=> \(x=133-125\)
=> \(x=8\).Vậy \(x=8\)
\(b) 5(x+12)+22=92\)
\(=> 5(x+12)=92-22 \)
\(=>5(x+12)=70\)
\(=> x+12=70.5\)
\(=>x+12=350\)
\(=> x=350-12\)
\(=> x=338\).Vậy \(x=338\)
