Dễ thương ghê :<

x . 49 + x : 10 = 20,6

x . (49 + 1/10) = 20,6

x. (4 + 11) = 36

x . 15 = 36

x = 36 : 15

x = 12/5

a) X x 16,01 - X : 100 = 76

a) X(16,01-0,01)=76

X x 16 = 76

X = 4,75

b) X x 4 + X x 11 = 36

X ( 4 + 11 ) =36

X x 15 = 36

X = 2,4

\(x:0,25+x\times11=36\\ \Rightarrow x\times4+x\times11=36\\ \Rightarrow x\times\left(4+11\right)=36\\ \Rightarrow x\times15=36\\ \Rightarrow x=\dfrac{36}{15}\)

x : 0,25 - x:0,25 =36

=>0=36 (vô lí)

=>đề sai khỏi làm

<=>x*(0,25-2,5)=36

​<=>x*(-2,25)=36

​​<=>x=36:(-2,25)

​<=>x=-16

​Tk mình nhé bn!

X x 0,25 -X x 2,5 = 36

X x ( 0,25 - 2,5 )= 36

X x (- 2, 25 )=36

X=-16

P/s tham khảo nha

\(0,25x-2,5x=36\)

\(-2,25x=36\)

\(x=-16\)

vậy \(x=-16\)
