Answer 1

HeYa❤️...

Answer:

$\frac{x}{3} + 1 = \frac{7}{15} \\ \\ \frac{x + 3}{3} = \frac{7}{15} \\ \\ 15(x + 3) = 21 \\ \\ 15x + 45 = 21 \\ \\ 15x = - 24 \\ \\ x = \frac{ - 24}{15} \\ \\ x = \frac{ - 8}{5}$

Answer 2

Answer:

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

Step-by-step explanation:

Solving the equation:

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

move the +1 to the other side of the equal sign

NOTE : moving a number from one side of the equal sign to the other changes the sign of the number. ( eg : +1 becomes -1 )

$\frac{x}{3} = \frac{7}{15} - 1$

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

make x the subject of formula :

x = $-\frac{8}{15} * 3$

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