Tìm x biết:
a) (2x-4).(3x+12)=0
b) 697:\(\frac{15x+364}{x}\)=17
Tìm x biết :
697 : ( 15x + 364 ) : x = 17
(15x+364):x=697:17(x khác 0)
Tìm x :
a) [ ( x + 32 ) - 17 ] * 2 = 42
b) [ 61 + ( 53 - x ) ] * 17 = 1785
c) 697 : 15x + 364 / x = 17
d) 92 * 4 - 27 = x + 350 / x + 315
1, [(10-x). 2+5 ] : 3-2 = 3
2, 697: [(15x+364):x ] = 17
tìm x
a , x-4867=(175.2050.70):25+23
b , 697:15x + 364/x = 17
c , 92.4-27=x+350 / x+315
697:\(\frac{15x+364}{x}\)=41
tìm x
\(697:\frac{15.x+364}{X}=17\)
tìm x thuộc N biết ; 697:\(\frac{15.x+364}{x}\)=17
