a,697:[(15.x+364):x]=17
=>(15x+364):x=679:17=41
=>\(\frac{15x}{x}+\frac{364}{x}=41\)
=>\(15+\frac{364}{x}=41\)
=>\(\frac{364}{x}=41-15=26\)
=>\(x=\frac{364}{26}=14\)
b,92.4-27=(x+350):x+317
=>\(341=\left(x+350\right):x+317\)
=>\(\left(x+350\right):x=341-317=24\)
=>\(\frac{x}{x}+\frac{350}{x}=24\)
=>\(1+\frac{350}{x}=24\)
=>\(\frac{350}{x}=23\) => \(x=350:23=\frac{350}{23}\)
tìm x:
\(697:\frac{15.x+364}{x}=17\)
\(92.4-27=\frac{x+350}{x}+315\)
tìm x:
\(697:\frac{15.x+364}{x}=17\)
\(92.4-27=\frac{x+350}{x}+315\)
1.TÌM X,
A. 697:\(\frac{15.X+364}{X}\)=17
B. 92.4-27=\(\frac{X+350}{X}\)+315
tìm x
a , x-4867=(175.2050.70):25+23
b , 697:15x + 364/x = 17
c , 92.4-27=x+350 / x+315
697 : (15.a+364) \ a =17
92.4 -27 = (a+350) \ a+315
a)697:15x+364=17
b)92.4-27=x+350+315/x
c)720:[41-(2x-5)x]=23.5
trình bày ra nhé
32x - 1 - 23 = 19
\(697:\frac{15.x+364}{x}=17\)
\(92.4-27=\frac{x+350}{x}+315\)
Nhớ ghi cách làm ra nha
697:(15x+364):x=17
92.4-27=(x+350):x+315
720:(41-(2x-51)=23.5
(x+1)+(x+2)+(x+3)+...+(x+100)=5750
Tìm x:
1, tìm số tự nhiên x biết rằng
a, 720:[41-(2x-5)]=23.5
b, (x+1)+(x+2)+(x+3)+...+(x+100)=5750
2, tìm số tự nhiên a biết rằng
a,697:15.a+364 / a =17
b,92.4-27=a+350 /a +315
