Question

Cứu vs

2x+5x+12x +x=36

 

Answer 1

=>  x(2 + 5 + 12 + 1) = 36

=>  x.20 = 36

=>  x = 1,8

Answer 2

2x + 5x + 12x + x = 36 => x(2 + 5 +12 +1) = 36 => x.20 = 36 => x = 36 : 20 => x=9/5

vậy x= 9/5

Answer 3

\(2x+5x+12x+x=36\)

\(=>x\left(2+5+12+1\right)=36\)

\(=>20x=36\)

\(=>x=1,8\)
