Question

$solve \frac{15}{4 } - 7x = 9$
​

Answer 1

Answer

x = -3/4

$\frac{15}{4} - 7x = 9 \\ 7x = \frac{15}{4} - 9 \\ 7x = - \frac{21}{4} \\ x = - \frac{3}{4}$

Answer 2

Answer:

$\frac{15}{4} - 7x = 9$

$- 7x = 9 - \frac{15}{4}$

$- 7x = \frac{21}{4}$

$x = \frac{21}{4} \times ( - 7)$

$x = - \frac{ 3}{4}$
