Tìm x
a. 126 - 2x = 12 - ( -28 )
b. 25 - 5 ( x+1) = 30 - 125
cc. | 3x - 1| - 25 = 73
d . 2( x+ 2 ) - 6 = 120 - 4x
Tìm STN x, biết
1) (x + 2) - 2 = 0 2) (x + 3) + 1 = 7
3) (3x - 4) + 4 = 12 4) (5x + 4) - 1 = 13
5) (4x - 8) - 3 = 5 6) 3 + (x - 5) = 7
7) 8 - (2x - 4) = 2 8) 7 + (5x + 2) = 14
9) 5 - (3x - 11) = 1 10) 16 - (8x + 2) = 6
Tìm x
a, x : 46/15 = 13/12
b, -2/3x + 1/5 = 3/10
c, x : 13/3 = -2,5
d, 2/4x + 2/5x = 1
