If (x/3) + 1 = ( 7/15) then the value of 'x' is
(iii) 7/5
(iv) 3
(i) 22/5
(ii) —8/5​

Answer 1

Answer:

$\frac{x}{3} + 1 = \frac{7}{15} \\ \\ 1 = \frac{7}{15} - \frac{x}{3} \\ \\ 1 = \frac{7 - 5x}{15} \\ \\ 15 = 7 - 5x \\ \\ 15 - 7 = - 5x \\ \\ 8 = - 5x \\ \\ x = \frac{8}{ - 5} \\ \\ x = \frac{8 \times ( - 1)}{ - 5 \times ( - 1)} \\ \\ x = \frac{ - 8}{5}$
