solve it linear equations
pls anybody solve 4 b part and question no 5,Question , it's urgent​

Answer 1

Answer:

4 (b)0

5 (a)-19/4

(b)-8/7

Answer 2

$4 \: b) = \: \frac{7x + 4}{5x + 2} = 2$

$7x + 4 = 2(5x + 2)$

$7x + 4 = 10x + 4$

$7x - 10x = 4 - 4$

$- 3x = 0$

$x = \frac{0}{ - 3}$

$x = 0$

$5 \: a) \: \frac{3x + 2}{x + 3} - 5 = 2$

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

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

$3x + 2 = - 3(x + 3)$

$3x + 2 = - 3x - 9$

$3x + 3x = - 9 - 2$

$6x = - 11$

$x = \frac{ - 11}{6}$

$5 \: b) \: \frac{3x + 2}{5} - 2x = 2$

$\frac{3x + 2}{5} - \frac{2x}{1} = 2$

$\frac{3x + 2 - 10x}{5} = 2$

$- 7x + 2 = 2 \times 5$

$- 7x + 2 = 10$

$- 7x = 10 - 2$

$- 7x = 8$

$x = \frac{8}{ - 7}$
