Tìm n biết \(697:\frac{15n+364}{n}\) = 17
tìm x thuộc N biết ; 697:\(\frac{15.x+364}{x}\)=17
a,(2n-3) chia hết cho (n+2)
b, 92 *4-27 n+350 trên n + 315
697:15n +364 trên n =17
tìm a thuộc N
697 : \(\frac{15a+364}{a}\)=17
\(\frac{15a+364}{a}\)=697:17
\(\frac{15a+364}{a}\)=41
15a+364=41a
26a=364
a=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
\(\frac{15x+364}{x}=697:17=41\)
\(15x+364=41x\)
\(364=41x-15x\)
\(26x=364\)
\(x=364:26=14\)
Tìm x biết: 697 : \(\frac{15\times a+364}{a}\) = 17
<=> \(\frac{15a+364}{a}=41\Leftrightarrow15a+364=41a\Leftrightarrow26a=364\Rightarrow a=14\)
Tìm x biết :
697 : \(\frac{15.x+364}{x}\)=17
\(697:\frac{15x+364}{x}=17\)
=> \(\frac{15x+364}{x}=697:17\)
=> \(\frac{15x+364}{x}=41\)
=> 15x+364=41x
=> 15x-41x+364=0
=> -26x+364=0
=> -26x=-364
=> x=-364:(-26)
=> x=14
Tìm số tự nhiên a, biết rằng:
\(697 : \frac{15\;.\;a + 364}{a} = 17\)
\(697:\frac{15a+364}{a}=17\)
\(\Leftrightarrow\frac{15a+364}{a}=41\Leftrightarrow15a+364=41a\Leftrightarrow15a-41a=-364\Leftrightarrow-26a=-364\Leftrightarrow a=14\)
Tìm a thuộc N biết
a) 697 : (15a+364/a) = 17
b) 92 . 4 - 27 = a+350/a + 315
Tìm x \(697:\frac{15x+364}{x}=17\)
\(697:\frac{15x+364}{x}=17\)
\(\left(=\right)\frac{15x+364}{x}=41\)
\(\left(=\right)15x+364=41.x\)
\(\left(=\right)41x-15x=364\)
\(\left(=\right)26x=364\)
\(\left(=\right)x=14\)
\(697:\frac{15x+364}{x}=17\)
\(\Rightarrow\frac{15x+364}{x}=697:17\)
\(\Rightarrow\frac{15x+364}{x}=41\)
\(\Rightarrow15x+364=41x\)
\(\Rightarrow41x-15x=364\)
\(\Rightarrow26x=364\)
\(\Rightarrow x=364:26\)
\(\Rightarrow x=14\)
Vậy x = 14
