13.104 : x - 8.75 = 6.88
13.104/y-8.72=6.88
13,104:y-8,72=6,88
13,104:y=6,88+8,72
13,104:y=15,6
y=13,104:15,6
y=0,84
13,104 / y - 8,75 = 6,88
13,104/y = 6,88 + 8,75
13,104 /y = 15,63

x + 8.75 = 8.75 x = ........................... vì ...................
3\4 + x = 12\16 ; x = ....................... vì ......................
x + 8,75 = 8,75
x = 0 vì 8,75 - 8,75 = 0 = x
3/4 + x = 12/16
x = 0 vì 12/16 - 3/4 = 3/4 - 3/4 = 0 = x
x bằng 0 vì 8.75 - 8.75 = 0
x bằng 0 vì \(\frac{12}{16}\)- \(\frac{3}{4}\)= 0
tk nha , Chúc bạn học giỏi
8.75 x X + 12,5 x X =20
X x ( 8,75 + 12,5 ) = 20
X x 21,25 = 20
X = 20 : 21,25
X= \(\frac{16}{17}\)
Đúng 100%
Đúng 100%
Đúng 100%
8.75*X+12.5*X=20
\(\Rightarrow\)X*(12.5+8.75)=20
\(\Rightarrow\)X*21,25=20
\(\Rightarrow\) X=20:21.25
\(\Rightarrow\) X=16/17
8.75 x X + 1.25 x X =20
8.75 x X + 1.25x X =20
X x ( 8.75+ 1.25) = 20
X x 10 =20
X = 20 : 10
X = 2
8.75*x+1.25*x=20
\(\Rightarrow\) (8,75+1,25)*x = 20
\(\Rightarrow\) 10*x=20
\(\Rightarrow\) x = 2
