8.75 x X + 1.25 x X =20
8.75*x+1.25*x=20
\(\Rightarrow\) (8,75+1,25)*x = 20
\(\Rightarrow\) 10*x=20
\(\Rightarrow\) x = 2
mk nhanh nhất

8.75 x X + 1.25 x X = 20
Hỏi X = ?
8,75*x+1,25*x=20
x*(8,75+1,25)=20
x*10 =20
x =20:10
x =2
Tìm X
8.75 x X + 1.25 x X =20
\(8,75\cdot x+1,25\cdot x=20\)
\(=>x\cdot\left(8,75+1,25\right)=20\)
\(=>x\cdot10=20=>x=2\)
k nha xin đó
8,75 . x + 1,25 . x = 20
x .( 8,75 + 1,25 ) = 20
x . 10 = 20
x = 20 : 10
x = 2

8.75 nhan x+1.25 nhan x=20
8.75*x+1.25*x=20
Giải hộ mình nha các bạn
\(8,75\text{ x }x+1,25\text{ x }x=20\)
\(\left(8,75+1,25\right)\text{ x }x=20\)
\(10\text{ x }x=20\)
\(x=20\text{ : }10\)
\(x=2\)
\(8.75\cdot x+1.25\cdot x=20\)
\(\left(8.75+1.25\right)\cdot x=20\)
\(10\cdot x=20\)
\(x=20:10\)
\(x=2\)
8.75*x+1.25*x=20
=(8.75+1.25)*x=20
=10*x=20
x=20:10
x=2
8.75 x y + 1.25 x y = 26.3
8,75 x y + 1,25 x y = 26,3
(8,75 + 1,25 ) x y = 26,3
10 x y = 26,3
y = 26,3 : 10 ( TTS )
y = 2,63
7/11 +3/4 +4/11 +1/4
0.8 x X =1.2 x 10
X - 3/5 = 1/10
8.75 x X + 1.25 =20
4/X = 1/5
6+X/33 =7/11
các bn giúp mik nhé
a) =(7/11+4/11)+(3/4+1/4) b)=>4/5x=12 c)=>x-6/10=1/10 d)tự làm e)=>4/x=4/20 f)=>198/33+x/33=21/33
=1+1 x=12.5/4 x=1/10+6/10 =>x=20 =>x=21-198
=2 x=15 x=7/10 =>x=-177
