please answer the question ​

Answer 1

Given:

$\dfrac{2- 7x}{1- 5x}} = \dfrac{3 + 7x}{4 + 5x}$

To Find:

The value of x

Solution:

$\dfrac{2- 7x}{1- 5x}} = \dfrac{3 + 7x}{4 + 5x}$

Cross multiply:

$(2 - 7x) (4 + 5x) = (1 - 5x)(3 + 7x)$

Expand:

$8 + 10x - 28x - 35x^2 = 3 + 7x - 15x - 35x^2$

Combine like terms:

$8 -18x - 35x^2 = 3 - 8x - 35x^2$

$8 -18x = 3 - 8x$

$10x = 5$

Divide by 10 to solve for x:

$x = \dfrac{1}{2}$

Answer: x = 1/2
