Question

Tìm x:

 x:0,25+x:0,01+x:0,5+x=214

Answer 1

x:0,25+x:0,01+x:0,5+x=214

\(\Rightarrow x\times4+x\times100+x\times2+x=214\)

\(\Rightarrow x\times\left(4+100+2+1\right)=214\)

\(\Rightarrow x\times107=214\)

\(\Rightarrow x=214:107\)

\(\Rightarrow x=2\)

Answer 2

x:0.25+x:0.01+x:0.5+x=214

x:(0.25+0.01+0.5+1)=214

x:1.76=214

x=214*1.76

x=376.64

Answer 3

X : 0,25 + X : 0,01 + X : 0,5 +X = 214

X =X * 4 + X * 100 + X * 2 +X = 214

X = X * [ 100 + 4 +2 +1 ] = 214

X = X * 107 = 214

X = 214 : 107

X = 2

Answer 4

 x:0,25+x:0,01+x:0,5+x=214

x*4+x*100+x*2+x=214

x*(4+100+2+1)=214

x*107=214

x=2
