\(92.4-27=\frac{a+350}{a}+315\)
\(368-27=\frac{a+350}{a}+315\)
\(368-27=1+\frac{350}{a}+315\)
\(341=\frac{350}{a}+316\)
\(341-316=\frac{350}{a}\)
\(25=\frac{350}{a}\)
\(25a=350\)
\(a=350:25\)
\(a=14\)
\(92.4-27=\frac{a+350}{a}+315\)
\(\Rightarrow368-27=1+\frac{350}{a}+315\)
\(\Rightarrow341-1-315=\frac{350}{a}\)
\(\Rightarrow25=\frac{350}{a}\)
\(\Rightarrow a=\frac{350}{25}=14\)
\(a.697:\dfrac{15a+364}{a}=17\\ =>\dfrac{15a+364}{a}=697:17=41\\ =>41a=15a+364\\ =>41a-15a=364\\ =>26a=364=>a=\dfrac{364}{26}=14 \\ b.92.4-27=\dfrac{a+350}{a}+315 \\ =>92.4-27-315=\dfrac{a+350}{a}\\ =>26=\dfrac{a+350}{a}\\ =>26a=a+350=>25a=350 \\ =>a=14\)
a) \(697:\frac{15a+364}{a}=17\)
\(\Rightarrow\frac{15a+364}{a}=697:17\)
\(\Rightarrow\frac{15a+364}{a}=41\)
\(\Rightarrow15a+364=41a\)
\(\Rightarrow364=26a\Rightarrow a=364:26\)
\(\Rightarrow a=14\)
b)
\(368-27=\frac{a+350}{a}+315\)
\(341=\frac{a+350}{a}+315\)
\(\left(a+350\right):a=341-315\)
\(\left(a+350\right):a=26\)
\(a+350=26a\)
\(\Rightarrow350=25a\)
\(\Rightarrow a=14\)
92X4-27=\(\dfrac{a+350}{a}\)+315
=>341=1+\(\dfrac{350}{a}\)+315=316+\(\dfrac{350}{a}\)
=>\(\dfrac{350}{a}\)=341-316=25
=>a=\(\dfrac{350}{25}\)=14
