\(697:\frac{15.x+364}{X}=17\)
tìm x thuộc N biết ; 697:\(\frac{15.x+364}{x}\)=17
Tìm x:
697:\(\frac{15.x+364}{x}\)=17
\(=>\frac{15.x+364}{x}=697:17\)
\(=>\frac{15.x}{x}+\frac{364}{x}=41\)
\(=>15+\frac{364}{x}=41\)
\(=>\frac{364}{x}=41-15\)
\(=>\frac{364}{x}=26\)
\(=>x=364:26\)
\(=>x=14\)
\(\Rightarrow\frac{15.x+364}{x}=697:17\)
\(\Rightarrow\frac{15.x+364}{x}=41\)
\(\Rightarrow15.x+364=41.x\)
\(\Rightarrow364=26.x\)
\(\Rightarrow x=14\)
tìm x biết \(697:\frac{15.x+364}{x}=17\)
\(697:\frac{15\cdot x+364}{x}=17\)
=> \(\frac{15\cdot x+364}{x}=697:17=41\)
=> \(15\cdot x+364=41x\)
=> \(15x+364=41x\)
=> \(364=41x-15x\)
=> \(364=26x\)
=> \(x=364:26=14\)
\(\Rightarrow\frac{15x+364}{x}=697:17=41\)
\(\Rightarrow15+\frac{364}{x}=41\)
\(\frac{364}{x}=41-15=26\)
x = 364 : 26 = 14
\(\frac{15x+364}{x}=697:17=41\)
\(15x+364=41x\)
\(364=41x-15x\)
\(26x=364\)
\(x=364:26=14\)
