\(6\times\left(5\times x+35\right)=330\)
`\Rightarrow 5 \times x + 35 = 330 \div 6`
`\Rightarrow 5 \times x + 35 = 55`
`\Rightarrow 5 \times x = 55 - 35`
`\Rightarrow 5 \times x = 20`
`\Rightarrow x = 20 \div 5`
`\Rightarrow x=4`
Vậy, `x=4.`
6.(5.x+35)=330
Bài 6: Tìm X biết :
a) X : [(1800+600) :30] = 560 : (315-35)
b) [(250-50) : 15] : X = (450-60) :130
c) (158- X) : 7 = 20
d) 231-(X - 6) = 1339:13
e) 70-5 (2xX-3) = 45
f)156 - (x +61) = 82
g) 6x(5xX+35) = 330
h) 936 - (4xX +24) =72
6.(x+35)=330
Tìm x:
a) 70-5.(2x-3)=45
b) 6.(5.x+35)=330
c)936-(4.x+24)=72
d)(x+1)+(x+3)+(x+5)=30
e)(x+2)+(x+4)+(x+6)+.....+(x+100)=2650
Tìm x:
6+12+8+...+6x=330
tìm x
70-5 .(2x-3) =45
156 -(x cộng 61 ) =82
6.(5x cộng 35) =330
936- (4x cộng 24) =72
tim so nguyen x: (12x-1)(6x-1)(4x-1)(3x-1)=330
Bài 1: Tìm x : A) 25%x+4x=35-0,75x
B) 3/4.(x-2) - 1/2.(6-2x)=1/6x + 5
C) -1/2.(3x+5) - 2/3.(9-6x)= 3/5.(x-10) - 3
D) (1/4x - 1,5) + (5/6x-3) - (5/8x-0,5)= -4,5
tìm x
890 : x = 35 dư 15
1482 ; x + 23 = 80
15 -5 x ( x -1 ) = 10
6x - 5 = 613
