( 32/46 x Y - 16/23 x 21/23) : ( 12/25 + 5/8 x 13/6 - 36/45 : 3 ) = 0
tim Y
1.tim x
a) ( 17x-25):8+65=81
b) 720 :[41-(2x-5)]=8.5
c) 231-(x-6)=1339:13
tim x biet 3/5 - 1/4 : x = 25/100
3/5-1/4:x=25/100
tim x
Tim x biet
a) 25,4 - \(\frac{1}{4}\): x + 1250%=37,5
b) \(3\frac{1}{8}\):(\(\frac{2}{5}\)- x) nhan \(\frac{8}{25}\)=3
Tim x:
a) \(\dfrac{13+x}{20}=\dfrac{3}{4}\)
b) \(\dfrac{23-x}{25}=\dfrac{4}{5}\)

2. Tim x tren y biet
a. x/y + 4/5 = 8/6
b. x/y - 4/5 = 2/3
c. 5/8 * x/y = 5/12
d. x/y : 2/9 = 3/8
