Bài 1: tìm x TRÌNH BÀY LUÔN
1) 2x+20=122
2) 26-2x=20
3) 5x+205=295
4) 75+12:x=81
5) 3x-7=14
6) 45:(12-x)=3
7) 172-2.(x-30)=94
8) (x+52)-27=54
9) 72:3(x-3)=6
10) 19-(4x+1)=10
x/2 = 5/y = z/8 = 10/40
giải: x/-2 = 10/40 suy ra x.40=10.(-2) = -20
x = (-20) : 40 = 0,5
còn 2 phép tính nữa ai giúp mik vs
Tìm x:
x:0,25+x:0,01+x:0,5+x=214
Tìm x
a,(4x-5).(\(\dfrac{5}{4}\)x-2)=0 b,(\(\dfrac{1}{12}\)+\(3\dfrac{1}{6}\)-30,75)x-8=(\(\dfrac{3}{5}\)+0,415+\(\dfrac{1}{200}\)):0,01
Tìm x
1) 5x - 16 = 40 + x
2) 4x - 10 = 15 - x
3) 3x - 6 = 5x + 2
4) 15 - x = 4x - 5
5) x - 15 = 6 + 4x
6) -12 + x = 5x - 20
7) 7x - 4 = 20 + 3x
8) 5x - 7 = -21 - 2x
9) x + 15 = 20 - 4x
10) 17 - x = 7 - 6x
Tìm x
X : 0,25 + x : 0,5 + x + x + 0,01 = 214
Giúp vs mik nha
