Question

solve 15/4 minus 7x = 9​

Answer 1

Answer: x= 3

Explanation:

15-7x=21

x=21/7

=3

Answer 2

Answer:

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

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

$\frac{15}{4} - \frac{28x}{4} = 9$

$\frac{15 - 28x}{4} = 9$

$15 - 28x = 9 \times 4$

$- 28x = 36 - 15$

$- 28x = 21$

$x = - \frac{21}{28}$

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