tìm x biết
1) x=-1/2 + 3/4 2) x - 1/5 = 2/11 3) x - 5/6 = 16/42 + -8/56
4) x/5 = 5/6 + -19/30 5) |x| - 1/4 = 6/18 6)x = -1/2 +3/4
7) x/15 = 3/5 + -2/3 8)11/8 + 13/6 = 85/x 9) x - 7/8 = 13/12
10) x - -6/15 = 4/27 11) -\(\dfrac{-6}{12}\)+ x = 9/48 12) x - 4/6 = 5/25 + -7/15
Tìm số nguyên x biết:
a. -4/3/5.2/4/23 < hoặc = x < hoặc = -2/3/5:1/6/15
b. -4/1/3.(1/2-1/6) < hoặc = x < hoặc = -2/3 ( 1/3-1/2-3/4)
