One third of a number is six more than one fourth of a number. What's the number

One third of a number is six more than one fourth of a number. What's the number

6 ÷ (1 / 3-1 / 4)
=6 △ 1 / 12
=6×12
=72

The equation of (1-6 / 1) x / 6 - (2 / x + 54) / 6 = 15 should be solved in detail

(1-1/6)x/6-(x/2+54)/6=15
(5/6 x-x/2-54)/6=15
(1/3x-54)/6=15
1/18x-9=15
x=(15+9)*18
=384

Solving the equation x △ 4 / 21 = 3 / 8

&Nbsp; X △ 4 / 21 = 3 / 8
&X = 3 / 8 times 4 / 21
X = 1 / 14

To solve the equation, 1 / 3: 1 / 20 = 5 / 9: X

1/3:1/20=5/9:x
x=1/20×5/9÷1/3
x=1/36×3=1/12

Two thirds x-20% x = 1 to solve the equation

2X/3-20X/100=1
2X/3-X/5=1
Multiply both sides by 15
10x-3x=15
7x=15
x=15/7

Solution equation: x-3 / 20 x = 8.5

x-3/20x=8.5
17/20x=8.5
x=8.5×20÷17=10

X × 1 / 3 × 6 / 7 = 4 x-20% x = 4 / 7
Two in all

X × 1 / 3 × 6 / 7 = 4
X * 2 / 7 = 4
X = 4 △ 2 / 7
x=14
X-20% x = 4 / 7
80% x = 4 / 7
X = 4 / 7 △ 80%
X = 5 / 7

[(1-3 / 1) x - 8] / [(1-5 / 2) x + 8] = 13 / 14 [[solving equation]] detailed explanation!

[(1-1/3)x-8]÷[1-2/5)x+8]=14/13
[2/3x-8]÷[3/5x+8]=14/13
2/3x-8=14/13(3/5x+8)
2/3x-8=42/65x+112/13
130x-1560=126x+1680
130x-126x=1680+1560
4x=3240
x=810

To solve the equation x-3 / 2 = 5 / X
X-3 / 2 = 5 / X
(x + 1 / 3-2 / x) = x & # 178; - 1 / 9

Double x (X-2)
3x=5x-10
x=5
By testing, x = 5 is the solution of the equation
1/(x+3)+2/(x-3)=1/(x+3)(x-3)
Multiply by (x + 3) (x-3)
x-3+2x+6=1
x=-2/3
The test shows that x = - 2 / 3 is the solution of the equation

Solve the equation x ^ 2-5 of 2x = 4 and 25 of 24

X ^ 2-5 of 2x = 4 and 25 of 24
x²-2/5x=124/25
x²-2/5x+(1/5)²=124/25+1/25
(x-1/5)²=5
x-1/5=±√5
x=1/5±√5
