x:0,25+x:0,01+x:0,5+x=214
\(\Rightarrow x\times4+x\times100+x\times2+x=214\)
\(\Rightarrow x\times\left(4+100+2+1\right)=214\)
\(\Rightarrow x\times107=214\)

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
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
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
