X=2
Vậy x=2
X + 78 * X + 25 * X - X * 4 = 78,6 + 121,4
X + 78 * X + 25 * X - X * 4 = 200
X * 1 + 78 * X + 25 * X - X * 4 = 200
X * ( 1+ 78 +25 - 4 ) = 200
X * 100 = 200
X = 200 : 100 ( Tìm thừa số )
X = 2
Tk mk nha
X + 78 x X + 25 x X - X x 4 = 78,6 + 121,4
X + 78 x X + 25 x X - X x 4 = 200
X x (1 + 78 + 25 - 4) = 200
X x 100 = 200
X = 200 : 100
X = 2
\(x+78\times x+25\times x-x\times4=78,6+121,4\)
\(x\times\left(1+78+25-4\right)=200\)
\(x\times100=200\)
\(x=200:100\)
\(x=2\)
Vậy x = 2
Matcha
X + 78 x X + 25 x X - X x 4 = 78,6 + 121,4
= x + ( 1 + 78 + 25 - 4 ) = 200
=> x x 100 = 200
x = 200 : 100
x = 2
Vậy , x = 2
X x 1 + 78 x X + 25 x X - X x 4 = 78,6 + 121,4
X x ( 78 + 1 + 25 - 4 ) = 200
X x 100 = 200
X = 200 : 100
X = 2
