b) \(3x+17=2\)

c) \(\left|x-1\right|=0\)

Answer 1

a)

b)

=>3x =2-17

=>3x =-15

=> x =-15:3

=> x =-5

c)

Answer 2

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
