To solve the fractional equation: 1.5x/x + 1-x / x + 6 = 4.2.x? + 1 / x + 2x / x? + 1 = 3

To solve the fractional equation: 1.5x/x + 1-x / x + 6 = 4.2.x? + 1 / x + 2x / x? + 1 = 3

1.5x/x+1-x/x+6=4.5x(x+6)-x(x+1)=4(x+1)(x+6);5x²+30x-x²-x=4x²+28x+24;x=24;2.x²+1/x+2x/x²+1=3(x²+1)(x²+1)+2x²=3x(x²+1);(x²+1)²-3x(x²+1)+2x...

When x = 3, y = 7, find the value of x 2 - 4 of fraction (XY + 2Y) - (X-2)

Since your topic is not clear, consider it in two cases
Solution 1:
When x = 3, y = 7:
(xy+2y)-[(x²-4)/(x-2)]
=y(x+2)-(x+2)(x-2)/(x-2)
=y(x+2)-(x+2)
=(y-1)(x+2)
=(7-1)(5+2)
=42
Solution 2:
When x = 3, y = 7:
(x²-4)/[(xy+2y)-(x-2)]
=(x+2)(x-2)/[y(x+2)-(x-2)]
=5/(7*5-1)
=5/34

Given that x + 2Y = 0 (x ≠ 0), find the value of 2XY + y 2 of fraction x 2 - XY

x+2y=0
x=-2y
(2xy+y²)/(x²-xy)
=y(2x+y)/[x(x-y)]
=y(-4y+y)/[-2y(-3y)]
=-3y²/6y²
=-1/2

Reduced to the simplest fraction: x 2 - xy-6y 2 in x 2 + xy-2y

X-3y is divided into X-Y, and the same factor is x + 2Y

Then 2x = - y ≠ 0, then the value of the fraction XY / x? - y? Is on-line

2x=-y
y/x=-2
XY / (x? - y?) (divide x ^ 2 by x ^ 2)
=(Y/X)/(1-(y/x)^2)
=2/3

Divide - Y - 2XY 2

4x²-y²/3x²y÷2x-y/xy
(=(2x+y)(2x-y)/3x²y×(xy)/(2x-y)
=(2x+y)/3x;
It's my pleasure to answer your questions and skyhunter 002 to answer your questions
If there is anything you don't understand, you can ask,

If x / y = 2, then the value of the fraction x? - Y / / XY

It should be (x? - y?) / XY, right
3/2

If 2x-1 of fraction xy = 3x? Y? 3, find m (expressed by formula containing XY) The number on the top is wrong If 2x-1 of xy = 2m of 3x? Y, find m (expressed by formula containing XY).

（2x-1）/xy=2m/(3X²Y³)
Is that the question?
2m=(3X²Y³)*(2x-1)/xy
m=3xy² *(2x-1)/2

Let X / y = 2 be a simple evaluation of fractions. Find x? - XY + 3Y? / x? + XY + 6y

If x / y = 2, then XY ≠ 0, Y / x = 1 / 2, then
（x²-xy+3y²）／（x²+xy+6y²）
Divide the numerator and denominator by XY
（x/y-1+3y/x）／（x/y+1+6y/x）
=（2-1+3/2）／（2+1+6/2）
=5/12
Hope to help you!

Solution: (xy-x 2) (1 / x + 1 / Y-X)

Here, oh, the best y
