y+y x 1/3 : 2/9 + y :2/7 = 252
y x 1 + y x (1/3 x 9/2 ) + y x 7/2 = 252
y x 1/1 + y x 3/2 + y x 7/2 = 252
y x (1/1 + 3/2 + 7/2 ) = 252
y x 6 = 252
y = 252 : 6
y = 42
tìm x :a,5/9xX-1=8/9,b,X+Xx1/3:2/9+x:2/7=252,c,2/5+3/5xX=2/3
tìm x
a) x+x* 1/3 : 2/9 + x :2/7= 252
b) (x+2)+ (x+5)+(x+8)+...+(x+32)=198
X + X x 1/3 : 2/9 + X : 2/7 = 252 . Tìm X
tính giúp nhé! ghi rõ lời giải. OK.
Bài 1 Tìm X
X+X×1/2:2/9+X:2/7=252
x+x*1/3:2/9+x:2/7=252
x + x * 1/3 : 2/9 + x : 2/7 = 252
tìm x biết
x + x * \(\frac{1}{3}\): \(\frac{2}{9}\)+ x :\(\frac{2}{7}\)= 252
\(x+x\cdot\frac{\frac{1}{3}}{\frac{2}{9}}+\frac{x}{\frac{2}{7}}=252\)
Tìm X
X+X x 3 : \(\frac{2}{9}\)+X :\(\frac{2}{7}\)=252
