Bài 1 :
a , x = 675
b , x = 1764
c , x = 0
Bài 2 :
a , x = 3 , 2 , 1 , 0
b , x = 6 , 5 , 4 , 3 , 2 , 1 , 0
c , x = 3 , 4
Bài 1:Tìm x
a, x:5=27\(x\)5
x:5=135
x =135\(x\)5
x =675
b, x:7=36\(x\)7
x:7=252
x =252\(x\)7
x =1764
c,x\(x\)132=312 x (5-3-2)
x\(x\)132=312x0
x\(x\)132=0
x =0:132
x =0

b) 6/5:x:5/4=10/15
6/5:x=10/15*5/4
6/5:x=5/6
x=6/5:5/6
x=36/25

x + 10 = 50 - 20
x + 10 = 30
x = 20
x + 10 - 5 = 20 + 20
x + 5 = 40
x = 35

\(a,\)\(x+x+2x=164\)
\(\Rightarrow4x=164\)
\(\Rightarrow x=41\)

a) x + 26 = 32
x = 32 - 26
x = 6
b) 30 - x = 10
x = 30 - 10
x = 20
\(a,x+26=32\\ x=32-26\\ x=6\)
\(b,30-x=10\\ x=30-10\\ x=20\)

a) x - 5 = 0
=> x = 0 + 5
=> x = 5
b) x . 7 = 14
=> x = 14 : 7
=> x = 2
c) x + 2 = 6
=> x = 6-2
=> x = 4
Ai k mik mik k lại


x - 199 = 3 . 300 : 5
=> x - 199 = 180
=> x = 180 + 199
=> x = 379
x−199=3x300:5
\(\Rightarrow x=900:5+199\)
\(\Rightarrow x=450+199\)
\(\Rightarrow x=649\)
Hok tốt!

a) 3136 + x = 5315 b) x x 5 = 8725
x = 5315 – 3136 x = 8725 : 5
x = 2179 x = 1745.
