Question

$\frac{x}{3} +1 = \frac{7}{15}$
solve this question ​

Answer 1

$\frac{x}{3} +1 = \frac{7}{15} \\ \frac{x}{3} = \frac{7}{15} - 1 \\ \frac{x}{3} = \frac{7 - 15}{15} \\ \frac{x}{3} = \frac{ - 8}{15} \\ cross \: multiply \: it \\ x = \frac{ - 8 \times 3}{15} \\ x = \frac{ - 24}{15} \\ x = \frac{ - 8}{5}$

Answer 2

$\frac{x}{3} + 1 = \frac{7}{5}$

$\frac{x}{3} = \frac{7}{5} - 1$

$\frac{x}{3} = \frac{7 - 15}{5}$

$\frac{x}{3} = \frac{ - 8}{5}$

$x = \frac{ - 8}{5} \times \frac{3}{1}$

$\frac{ - 24}{5}$

$\frac{ - 24}{5}$
