tim x 52x-3-2×52 = 52×3
Tim x biet : (x+2)+(x+4)+.....+(x+52)=698
52×x-3-2×52 = 52×3
Tim x:
a,(62-3x):4=8
b,3(26+4x)-50=52
tim x,y e Z
2x+8y=52
tim x
12+x=28
26.x=52
Tìm y(k tim x đâu nha)
52 x (y : 78 ) = 3380
52 x X - 3 x 52 = 53 x 3
Tim x
a) ( x - 78) .26 =40
b) 39 . (x-5) =39
c) 30- ( 52 - x) =90
d) (x-12) : 5 =2
