a) 2x−35=15
=>2x =15+35
=>2x =50
=>x =50:2
=> x =25
b) 3x+17=2
=>3x =2-17
=>3x =-15
=> x =-15:3
=> x =-5
c) |x−1|=0
=> x-1=0
=>x =1
a) 2x-35=15
2x=15+35
2x=50
x= 50 : 2
x=25
Vậy x = 25
b) 3x + 17 = 2
3x= 2-17
3x= -15
x=-15 : 3
x= -5
Vậy x= -5
c) | x-1 | = 0
\(\Rightarrow\) x-1 = 0
\(\Rightarrow\)x = 0+1
\(\Rightarrow\)x=1
Vậy x=1
