Question

Solve the following equations and verify the result in each case .
$a. \: \: \frac{5x - 4}{8} - \frac{x - 3}{5} = \frac{x + 6}{4}$
$b. \: \: \frac{2x + 5}{3x + 4} = 3$
$c. \: \: \: x - \frac{3}{5} = \frac{7}{5}$
$d. \: \: 0.5x + \frac{x}{3} = 0.25x + 7$
please help me please ​

Answer 1

Step-by-step explanation:

b)

$\frac{2x + 5}{3x + 4} = 3$

$2x + 5 = 3(3x + 4)$

$2x + 5 = 9x + 12$

$5 - 12 = 9x - 2x$

$- 7 = 7x$

$x = - 1$

$x - \frac{3}{5} = \frac{7}{5}$

$x = \frac{7}{5} + \frac{3}{5}$

$x = \frac{10}{5}$

$x = 2$
