Question

pls solve them in the copy and send me the answer ​

Answer 1

Step-by-step explanation:

1)

$\frac{(5x - 7)}{3x} = 2$

$5x - 7 = 6x$

$5x - 6x = 7$

$- x = 7$

$x = - 7 \: \: \: \: \: \: \: \: \: \: ans$

2

$\frac{2x + 5}{x + 4} = 1$

$2x + 5 = x + 4$

$2x - x + 5 \: = 4$

$2x - x = 4 - 5$

$x = - 1 \: \: \: \: \: \: \: \: \: \: \: \: \: ans$

3)

$\frac{2x}{3x + 1} = - 3$

$2x = - 3 \times (3x + 1)$

$2x = - 9x - 3$

$2x + 9x = - 3$

$11x = - 3$

$x = - \frac{3}{11} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: ans$

4)

$\frac{2x}{3x - 2} = \frac{5}{9}$

Cross multiplication method =

$2x \times 9 = 5 \times (3x - 2)$

$18x = 15x - 10$

$18x - 15x = - 10$

$3x = - 10$

$x = - \frac{10}{3} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: ans$
