Bài 8. Tìm số nguyên x biết:
1/ -16 + 23 + x = - 16 2/ 2x – 35 = 15
3/ 3x + 17 = 11 4/ │x - 1│= 0
5/ -13 .│x│ = -26 6/ (2x – 5) + 17 = 6
7/ 10 – 2(4 – 3x) = -4 8/ - 12 + 3(-x + 7) = -18
9/ 24 : (3x – 2) = -3 10/ x.(x + 7) = 0
11/ (x + 12).(x-3) = 0 12/ (-x + 5).(3 – x ) = 0
13/ |x| = 5 14) |x| < 2
15) |x| = -1 16) |x| =|-5|
17)|x +3| = 0 18) |x- 1| = 4
19) |x – 5| = 10 20/ |x+4| = 5 – (-1)
21/3x – 10 = 2x + 13 22) x + 12 = -5 – x
23) x + 5 = 10 –x 24) 12 – x
2 = 3
25) 2.(x-1) + 3(x-2) = x -4 26) (x – 1)3 - 2 = -10
