Question

x/3+1=7/15..........................​

Answer 1

Answer:

x = -1.6

Step-by-step explanation:

$= > \frac{x}{3} + 1 = \frac{7}{15} \\ \\ = > \frac{x}{3} = \frac{7}{15} - 1 \\ \\ = > \frac{x}{3} = \frac{7 - 15}{15} \\ \\ = > \frac{x}{3} = - \frac{ 8}{15} \\ \\ = > x = 3 \times ( - \frac{8}{15} ) \\ \\ = > x = - \frac{8}{5} \\ \\ = > x = - 1.6$

Answer 2

Answer:

$\dfrac{x}{3}+1=\dfrac{7}{15}\quad :\quad x=-\dfrac{8}{5}\quad \left(\mathrm{Decimal}:\quad x=-1.6\right)$

Step-by-step explanation:

$\dfrac{x}{3}+1=\dfrac{7}{15}$

$\gray{\mathrm{Subtract\:}1\mathrm{\:from\:both\:sides}}$

$\dfrac{x}{3}+1-1=\dfrac{7}{15}-1$

$\gray{\mathrm{Simplify}}$

$\dfrac{x}{3}=-\dfrac{8}{15}$

$\gray{\mathrm{Multiply\:both\:sides\:by\:}3}$

$\dfrac{3x}{3}=3\left(-\dfrac{8}{15}\right)$

$\gray{\mathrm{Simplify}}$

$x=-\dfrac{8}{5}$
