Răspuns:
a) |2-x|=5
2-x = 5 2-x=-5
x= -3 x= 7
b) |x+3|=3
x+3 = 3 x+3=-3
x= 0 x= -6
c) |2-x| = 1
2-x=1 2-x=-1
x=1 x= 3
d) |2x +4| = 8
2x + 4 = 8 2x+4=-8
x= 2 x= -6
e) |3x-7|=5
3x-7=5 3x-7=-5
x=-4 x=2/3
f) |4-x|=11
4-x=11 4-x=-11
x= -7 x= 15
g) |-2x-6|=12
-2x-6=12 -2x-6=-12
x=-9 x= 3
h) |12-x| = -24
Nu se poate
i) Nu se poate
Sper ca te-am ajutat si nu uita de coronita
