chú ý :dấu chấm là dấu nhân và bài này là bài tìm x
1, Tìm x biết :
a, 2 * x - 138 = 8 * 9
b, { ( 6 * x - 72 ) : 2 - 84 ) } * 28 = 5628
c, 420 + 65 * 4 = ( x + 175 ) : 5 + 30
420+65*4=(x+175)/5+30
420 + 65 . 4 = ( x + 175 ) : 5 + 30
(32.15) : 2 = (x + 70) : 14 - 40
x - 4867 = ( 175 . 2050 . 76) + 25 + 23
giup em a
420 + 65 . 4 = ( x + 175 ) : 5 + 30
Giúp e nha
