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=0+1
x=1
tik nha
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
suy ra : x=1
tick nha!!!!!!!!!!
a) 2x - 35 = 15 b) 3x + 17 = 2 c) | x - 1 | = 0
2x = 15 + 35 = 50 3x = 2 - 17 = -15 \(\Rightarrow\)x - 1 = 0
x = 50/2= 25 x = -15 / 3 = -5 x = 0 + 1 = 1
